Tesla software update 2021.40 to add 'Live Camera Streaming'

By Nuno Cristovao

Tesla is on a roll with it's app lately. We've seen numerous releases since the app was updated to version 4.0 back in August. Just yesterday Tesla released version 4.2.0 with quick action buttons in one of its widgets and much better interior details of the vehicle.

With this same release, it looks like Tesla is starting to prepare to release a much anticipated feature in the near future, the ability to stream live video from your car.

Live Stream Video From Car

With the release of software update 2021.40, Tesla will allow you to stream live camera feeds from your car directly to your phone. You'll be able to view any of the cameras that are included in Dashcam or Sentry Mode, which include the front and rear cameras and the two side fender cameras.

When viewing the live feed from your car, you'll also be given the chance to save the video directly to the car. It's possible that Tesla will allow you to save it to your phone, but judging by the fact that Tesla is requiring your car to have a USB drive in order to stream video and that there is a new API endpoint to save dashcam footage, it's likely that the recorded video will be saved to your car instead of your phone.

View Sentry Clips and Dashcam Footage

In addition to being able to view live video from your car, and notably more useful. You'll now be able to remotely view Sentry Mode clips instead of having to wait until you get back to your car.

You'll likely be presented from a similar interface that appears in your car to view Sentry Mode and Dashcam clips and you'll be able to view and delete them.

Requirements

There will be a few requirements before you're allowed to stream video to your phone. Your car will obviously need to have the ability to use the Dashcam and Sentry Mode features, which require a vehicle with FSD HW 2.5 or higher. It will also require your vehicle to have software update 2021.40 or higher.

In addition, before being able to initialize the video stream, Tesla will require that your car be in park, have all doors closed and for no one to be in the car. Tesla is making these requirements presumably for privacy concerns around spying on individuals in a private environment.

Premium Connectivity Required

It's strongly suspected that your vehicle will need to be subscribed to Tesla's Premium Connectivity or be connected to WiFi in order to stream live video or remotely view Dashcam or Sentry Mode videos.

Tesla will very likely not introduce a higher priced connectivity option. Tesla already allows you to stream video services for unlimited periods. The bandwidth required to stream your car's cameras will be fairly small when compared to streaming video.

Limitations / Daily Limit

Tesla will impose a daily viewing limit on how long you can remotely monitor your vehicle with video. This is likely to prevent users from live streaming video for long periods of time. For example, if they went out to dinner, started a live stream and set their phone down.

I suspect the daily limit will be more than reasonable and you'll be unlikely to reach the limit unless you're trying to use your car as a security camera.

Talk to Car From Your Phone

When monitoring your car remotely, you'll be able to talk directly to your phone and have your voice come out of the car. This will require your vehicle to be equipped with the Pedestrian Warning System (PWS). Basically, if you have the Boombox feature, then you have the PWS.

In addition to being able to talk to the car from your phone, you'll also be able to honk the horn and flash your car's lights to alert anyone around your vehicle.

This snippet was found in the latest Tesla app:

"Tesla allows you to use your microphone to speak through your car or attach videos when scheduling service for your vehicle",

If you don't, then for some models Tesla can retrofit the PWS for a couple hundred dollars, although it's not available on all model years. Your car will need to already be wired to support the outdoor speaker.

I can see this feature being fun, but also useful. If there's someone seriously looking at your vehicle with ill intent, then what better way to deter them then to talk to them. They'll likely think that you're walking up to the car and walk away.

Of course, I'm sure there will be lots of humorous ways owners will use this feature as well.

Unfortunately, because Teslas do not (yet) have external microphones, this will be one-way audio. So you'll be able to talk to the individuals, but unfortunately unable to hear their surprised or funny reactions.

In-Car Purchases

As we talked about back in August, Tesla is adding in-car purchases. Features that you can buy directly on your phone today will become available in the vehicle as well. Features such as adding the FSD subscription, Performance Boost and others will now be only a couple taps away.

According to information in the latest iOS app, this feature will also be added in the 2021.40 software update.

As the owner of the vehilce, you'll see be able to limit in-car purchases as well, much like you can limit in-app purchases on other platforms.

Software updates have contained slightly less than usual lately as Tesla focuses on FSD and catching up on the new Model S software, but 2021.40 is surely to be an exciting release, even if this was the only feature in it.

Stay tuned for more.

Tesla LFP Batteries Can Now Be Warmed up While Supercharging Using Innovative Feature

By Karan Singh

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.

LFP Battery Heating

Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.

The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.

Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).

In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.

We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.

Tesla Included FSD V12.6.1 and V13.2.4 in the Same Update: What Caused This and What It Means

By Karan Singh
Not a Tesla App

Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.

FSD V13.2.4

A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.

While this update focuses on bug fixes, Tesla’s already working on bigger features for FSD V13.3, which we have already confirmed to include improvements to highway following and speed control.

FSD V12.6.1

FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.

While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.

It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.

Same Update, Multiple FSD Builds

What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.

The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.

While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.

What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.

While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.

While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.

Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
