does anyone know what is common function or usage of LoRa SX1262 on TWatchS3?

LoRa ^{(abbreviation stands for "Long Range")} is the communication protocol is designed for wireless long range communication at low power consumption, thus ^SX1262 module secures the relevant connection between this smart-watch and other LoRa capable devices.

Are you saying to me that it is now possible to have a merit wristband, a jade and a watch in the same device?

Probably, but let's see if someone test how everything works... maybe CryptoGuide from YT, he likes DIY bitcoin stuff.
I am not a big fan of this type of smart watches with their boring design, but support for code is more important.
If you ask me I would much rather use some retro design similar to casio watches.

I didn't read this thread for a while, so i just found out about commercial ESP32 smartwatch. I guess it's one more ways to hide or move Bitcoin wallet stealthily, although i doubt it'll work on border that may ask you to give access to all devices.

You can always flash the watch with regular watch firmware code, and load back Jade code when you cross the border.

And while we're at it, does anyone know what is common function or usage of LoRa SX1262 on TWatchS3?

Based on some information I found, it can work similarly to GPS to track the person wearing the watch. It's used for wireless communication and data transfer over longer distances. It can collect data about you, like health monitoring. The module can also become part of a wider system like smart homes, where it allows you to control various appliances from your watch.

Regarding Jade OG reading post here, that would be interesting.
I doubt, but it would be very helpful!

Interesting new update from Jade developers with adding support for esp32s3 DIY devices TTGO TWatchS3 and M5Stack CoreS3.
This means that anyone can finally have a bitcoin smart watch with Jade code for only around 40$.
Maybe someone from Jade is reading my posts because I was recently writing about this Wink

You will only know for sure if you try. Support personnel surely don't have such knowledge, but they could forward your inquiries to the right department. But you also have to keep in mind that there is no way for their developers to know if the wallet will be functional with a non-supported and untested hardware component if they haven't personally conducted similar tests.

I am thinking about trying it since the T-displayTTGO from Lilygo the model unit is ESP32 development board I found much cheaper one around $3 with no LCD and $7 with LCD much similar to T-display(Lilygo). It looks compatible since LNbits DIY hardware wallet mentions that they support T-display(LilyGo) or any version of ESP32 so maybe the blockstream jade firmware supports any ESP32 since they both have a similar model I'm sure it won't work on ESP32 with no LCD because you can't able to navigate but the one with LCD I believe it would work.

In case it doesn't work then I found another option not only LnBits support this but also uBitcoin Hardware wallet.
I found them from this video $10 bitcoin Hardware Wallet, DIY/FOSS/ESP32/easy build!

I got the warning, "Do not attempt to flash the Blockstream firmware to DIY hardware," so that means it's not possible?

The warning message on GitHub is to not flash a DIY firmware on an official Jade hardware wallet. It's surely there because they can't guarantee that your device will work as advertised and if you break it, it won't be covered by the warranty. The Jade doesn't come with a written warranty, but I have read that you can contact the support within a year of buying your device and there is an unofficial type of warranty and support.

I'm sure if I ask Blockstream they won't tell me the truth if their firmware will work because they're promoting LilyGo vendor.

The real question is, can it and does that particular model work? Have you checked this GitHub source? There is mention of some Lilygo displays there. If I were you, I would ask the Blockstream support or open a new issue on GitHub before buying the display to get feedback from them first.

Well, it just looks similar. I got the warning, "Do not attempt to flash the Blockstream firmware to DIY hardware," so that means it's not possible?
As you can see on the image, all components look the same, even on the back, which makes me think maybe the firmware from LilyGo will work on this unit?
I researched a bit yesterday and I heard that you need to replace the driver to be able to flash it with other custom firmware. I'm sure if I ask Blockstream they won't tell me the truth if their firmware will work because they're promoting LilyGo vendor.

In any case, I wouldn't use a DIY wallet on unsupported hardware to hold even only a few precious satoshis.
In case of any problems, expect way less support (if any) than if you went out using supported hardware.
I think the risk/reward ratio is too high for me.

I agree with filippone, I have been there and I can assure you that you don't wanna get in that position. There is no support at all. And it's perfectly normal because they couldn't offer support for every type of hardware.

It seems I found something similar with wireless wifi and Bluetooth module I was planning to try it if it can able to flash with the Blockstream jade firmware.

Has one here tried the lilygo T display model?

Here's a similar image that I found that I can buy near here in my country.

I saw a Twitter thread where they explain another reason why you should never connect the device to a PC:
As long as I know Jade is the only one able to do this.

The Blockstream Jade requires some type of connection to a PC when you first set it up to install its firmware. You can install the firmware either via the Blockstream Green software wallet or from Blockstream's download portal. There is a third (advanced) option that I have forgotten about. You can connect the device either via USB cable or Bluetooth to install the firmware. The same is true for firmware updates, with one difference being that you can install a firmware with disabled Bluetooth. If you do that, then you can only install new firmware updates by connecting the device via a cable.

You are right on one point here: having a signing device (a hardware wallet) and using it via Bluetooth is nonsense, given the amount of bad code an attacker can infect the Bluetooth stack with.
Also the attacker.

The platform I used to install the Jade software is the M5Stack module, lacks a photo camera.
Other solutions might include it.
So, my DIY Jade has a limitation regarding the airgapped usage, due to the inability to read QR codes.

That's too bad. I think Jade's airgapped functionality is the biggest strength of this device. Without it, it's a very limited hardware wallet without a secure element that has to rely on Blockstream's blind oracle and virtual secure element. It was recently discovered that this third-party server was breeched.

Indeed the airgapped operation is one of the main reason why this device is unique.

The main difference with the commercial solutions is the lack of a photocam, that downs allow to read QR.

Sorry, this part of your post confused me a bit. Are you saying that the DIY Jade when purchased disassembled doesn't come with a camera or that it does but the camera is of bad quality? If it's the latter, then I can confirm that. More precisely, it's not that the camera sucks to a degree of being useless, it's the software companion apps like Sparrow Wallet that can't scan the QR codes as well as they should. Another user also said that they were struggling with their Sparrow-Jade combo.

Are you using the Jade as a stateless signer and with what companion app?
