Custom BLE firmware for Hanshow E-Paper Shelf Labels / Price Tags using the TLSR8359 ARM SOC

You can support my work via PayPal: https://paypal.me/hoverboard1 this keeps projects like this coming.

As BLE can be enabled on the Telink TLSR8359 so i decided to make a custom firmware instead of reversing the stock firmware and its 2.4Ghz RF Protocol

This repo is made together with this explanation video:(click on it)

WebSerial Firmware flasher Tool: https://atc1441.github.io/ATC_TLSR_Paper_UART_Flasher.html

Compiling:

Python needs to be installed

Windows:

To compile under windows navigate with a command prompt to the "Firmware" folder

Enter "makeit.exe" and wait till the Compiling is done.

Linux:

Navigate with a Terminal into the "Firmware" Folder

Enter "chmod 777 -R ./"

Enter "make" and wait till the Compiling is done.

Flashing:

Open the Compiled .bin firmware with the WebSerial Flasher and write it to Flash.

On first Connection it is needed to Unlock the flash of the TLSR8359

Implements a BLE service for rendering images

This PR adds a BLE service & characteristic to which clients can write raw bitmaps.

Here's a sample of uploading an image with rbaron/pricetag-printer:

Upload failed

Hi, I've tried to upload the firmware but nothing changed. I've got no error messages but the image doesn't changed and the display did not even blink. I've used 2 different USB2TTL devices: based on cp2102 and ch340 chips. Is there any special thing that I must consider when making the upload ? Thanks.

Latest commit breaks previous working upload image using BLE

Last working stable commit is this one:

commit ff957594fc5747ecaf2c789c4abadef7b54c6be9 Author: atc1441 Date: Sat Jan 15 17:24:03 2022 +0100

Final CRC check working

Sorry but I would really like to recommend to make a feature branch where others can test and only after testing merge in master. Otherwise it's not so cool to break existing working behavior and just push it to main branch without letting at least other developers test the new feature, specially when you can now make a BLE OTA Firmware update (In case you remove Serial flashing cables) and you find out that it does not update. I could not update.

Barcode and unique identifier of each ESL tag

Hi @atc1441 ,

Would it be possible to have a:

const char * serial = "517714";

I was just analyzing the Barcode and it seems to me an unique identifier: Barcode location Which has this number in my device: Serial number

Then if we build this firmware using that constant, we could get a bluetooth name like: ESL_517714

My idea would be that we could scan this Barcode with a custom App and then we could automatically guess what is the device name. This can help to associate a device faster instead of browsing the hundred bluetooth around this days. But is just an idea, would be cool to have an unique serial and I just wanted to know where is the part of the code that generates the ESL_number. For this device the name I get is: ESL_545778

On another topic, I'm designing a small 3D-printable tiny placement, in case you want to place this vertically in your table with a nice inclination so you can see it more clearly. Will share it in Thingiverse once done and tested! It would be possible to add in the Readme also a link to https://cale.es/epaper/en/Hanshow/27 just to mention you can send the image using our free service?

cppcheck warning

https://github.com/atc1441/ATC_TLSR_Paper/blob/5a85959211960cedfa7b98291301c23ef63a250e/Firmware/src/obd.inl#L2314

    iPitch = pOBD->width;

    if (pDestination == NULL || pOBD == NULL || pOBD->ucScreen == NULL)
        return -1;

Looks fishy to me, too. :-)

[email protected] / BWR213 won't detect right version?

As reported in another thread here, the [email protected] version doesn't refresh its display properly. I flashed it thru UART and can now update it OTA. But the problem with the garbled display might come from not detecting the right BWR213 version. It displays it as BW213 which is not correct. Forcing the model version OTA, has no effect.

Hanshow [email protected]

I have a [email protected] model which is a larger display of 84.22*63.02 mm and a battery life of 5 years. I have no idea what CPU is on board. I opened up the battery departments, and it reveals a test connector with following labels:

| O | O | VCC  | GND  |
| O | O | TMS  | NRST |
| O | O | RXD  | TO?  |
| O | O | TEST | TXD  |

The labels on the second row are hidden behind the plastic casing, but I think they are correct, except TO? The other Stellar tags have a SWS connection that I don't see here. Any idea what TMS and TEST refer to, is one a SWS pin? Thanks for your great work on the Hanshow ESLs.

BLE not working on [email protected] E31H 401013

Hello!

I tried flashing various versions of this firmware with no luck getting BLE working, flashing works as flashing some test firmware that makes LED flash works.

How exactly is BLE working with TLSR8359? How can we test it's presence in hardware?

Thank you

i2c NFC datasheet?

I saw in the code there was some written for the initialisation of the NFC chip. I do want to expand this myself.

On the internet there isn't anything to find or how to address this bus or to write to the EEPROM. Anyone here have a non Chinese datasheet with the bus and register information on it?

Enhancement: Over the air update using miniz compressed bin

I have to check it's possible to do it in the Frontend javascript side. miniz is also what Espressif uses and it's quite stable.

$ ./miniz c ATC_Paper.bin ATC.z miniz.c version: 10.1.0 Mode: c, Level: 9 Input File: "ATC_Paper.bin" Output File: "ATC.z" Input file size: 107812 Total output bytes: 48047 Success.

So if it would be possible to implement this the BLE flashing over the air can take half the time and it would be then decompressed when it arrives to the device. Of course we need to check if there is enough RAM to do that, but I think it might be possible. Are this ones the right specs for the TLSR8358 SOC ?

Just an enhancement idea. I will research if it's possible to compress with miniz in the javascript frontend. Otherwise it's just a very fast command line action (the miniz executable weights 159K)

Firmware doesn't work on [email protected] E31HA 401011

Hi,

The included firmware doesn't display anything and doesn't advertise BLE. I have confirmed the firmware does run by toggling the red LED in main.c.

It does seem my [email protected] display's have slightly different product codes than yours but have the same PCB text. I have been able to get working firmware on the display by rewriting the epd_driver_demo in the TLSR8359 SDK to support the display.

The displaying part might be because of a different EPD display, but that doesn't explain the tag not advertising BLE because it is a TLSR8359 and the same PCB.

Do you have any idea on what might be wrong?

Also, I had to change line 4 of the makefile: TC32_COMPILER_PATH := tc32_windows\\bin\\ to TC32_COMPILER_PATH := tc32_windows/bin/ because of error /usr/bin/sh: tc32_windowsbintc32-elf-gcc: command not found

running Python 3.9.6 on Windows 10
