I'm having trouble building the example project for an ESP-C6(-DevKitC-1). I'm completely new to ESP-IDF so I may be doing something wrong, but I'm not sure how to debug.

I'm using VS Code with the ESP-IDF extension. I've cloned this repo (e23be3a) and the master branch of ESP-IDF (espressif/esp-idf@4fc2e5c).

When I click the build button in VS Code, here's the output I get:

I'm not entirely sure how to interpret these errors (I'm also a C++ newbie). It's also not clear to me if I need a specific commit of ESP-IDF to build this (since I can see there have been many commits mentioning openthread in ESP-IDF over the last few weeks, since this repo was last updated).

Any pointers would be appreciated. Thanks!

Answer 1 · 2023-07-17T05:33:01.000Z

@DanTup Seems you were trying to run the basic_thread_border_router on ESP32-C6 single SoC, but it is not supported.

The ESP Thread BR is based on the two SoCs solution, BR and OT core stack run on host SoC Wi-Fi (ESP32-S3), OT RCP runs on 802.15.4 SoC (ESP32-H2). Could you please run the example following the docs: https://docs.espressif.com/projects/esp-thread-br, you can either purchase a ESP Thread Border Router board, or setup the same connection between S3 and H2 modules (schematic).

It's possible to run ot_br on ESP32-C6 single SoC, but it's only a prototype, and not recommended for productization as documented in its readme:

The example could also run on a single SoC which supports both Wi-Fi and Thread (e.g., ESP32-C6), but since there is only one RF path in ESP32-C6, which means Wi-Fi and Thread can't receive simultaneously, it has a significant impact on performance. Hence the two SoCs solution is recommended.

The basic_thread_border_router supports the two SoCs board only.

Answer 2 · 2023-07-17T11:12:52.000Z

@chshu I only currently have ESP32-C6s right now - I had been hoping to use 2x ESP32-C6 for now - is that not supported?

I plan to purchase the Thread Border Router board, but it's currently out of stock on Aliexpress (which is the only place I can find it) and I was informed it won't be back until August. I was trying to see if I could set something up to play around with in the meantime.

Answer 3 · 2023-07-18T06:15:12.000Z

@DanTup Hi, could you please pull the latest code for the esp-thread-br, we updated the mdns version just now and there should not be any compiling errors.
For your questions: could 2x C6 be supported by this repo? the answer should be yes, you can have a try, but you need to connect the two boards together manually. Refer to the pin map here: standalone-modules.

Answer 4 · 2023-07-24T09:21:59.000Z

Similar problem occurred while trying to build project for ESP32C6.
There aren't messages about mdns but the are problems with rcp.

Answer 5 · 2023-07-26T18:34:31.000Z

Yep, I'm seeing the same errors as @Gonta01 above (but no longer errors about mdns).

It's still very possible I'm doing something wrong. I tried to order some ESP32-H2 but the order was rejected by Mouser because of export restrictions (apparently they can't ship it from the US to the UK). Currently the only option I have is using ESP32-S2 and/or ESP32-C6 boards.

Answer 6 · 2023-09-08T02:39:46.000Z

@DanTup @Gonta01 The default configuration in the example works as is on the ESP Thread Border router board. Please follow the docs here for any customized configurations: https://docs.espressif.com/projects/esp-thread-br/en/latest/dev-guide/build_and_run.html#configure-esp-thread-border-router

Answer 7 · 2023-11-24T23:00:50.000Z

Sorry I never responded here sooner. I ended up ordering the Border Router board and following these instructions using the latest code, and I had no errors building :-)

I did hit a really strange issue where booting the BR would cause a server on my network to reboot all of its kubernetes pods though - I opened an issue at #45 with some questions to try and better understand exactly what the BR is doing.
