Compile Errors when using ESP32C6

[dersvenni]

Hello,
i got an xiao ESP32C6 board and try to use the nuki BLE library and got many compiling errors with redefinition etc.
As i saw the library should already support the C6 is that correct ?

Best wishes

Yes, the library supports the ESP32-C6 and any other board that is supported by ESP-IDF and Arduino-ESP32.

Working implementation can be found at https://github.com/technyon/nuki_hub.

We use Arduino as a ESP-IDF component though and esp-nimble-cpp instead of NimbleBLE (both by h2zero).

Thanks Iranl,
i worked now a bit and updated Nimble to 2.3.6 this helps with the redefinition errors but the BLE Scanner i think is now the Problem , because of the Higher Version. I saw the Nuki Hub implementation on GIT but i want to use this library here, as i do not need all the MQTT Stuff. I create a fingervein reader device which is working fine with your library on a S3 and i only would try it on a c6, because on the s3 i have sometimes problems to open the web server which is running in parallel of the BLE. Maybe the BLE Scanner will be updated someday so i can test.
Thank you very much.

We have updated BLEScanner to work with more recent versions of esp-nimble-cpp and NimbleBLE.

We haven't upstreamed these changes though.

You can find our modified version in https://github.com/technyon/nuki_hub/tree/master/lib/BleScanner

Excellent, i took the updated BLE Scanner and now only 2 Problems have to been solved ;)

[iranl]

We maintained compatibility with older versions of Nimble using a macro.

Add the following to the top of BleScanner.cpp

#define BLESCANNER_USE_LATEST_NIMBLE

Hi iranl,

thanks, that was the hint i needed.
Now it is working.

Thanks for your help and hints.

Hi Iranl,
today i have tried to pair my Nuki Go with the ESP32C6 but i cannot get it to pair.
The scanner finds the UUID of the Pairing Service, so far i can see in the logs.
Do you have any idea ?
As i wrote i copy the BLE Scanner from the link you send and use the latest Arduino Nimble Version 2.3.6.
All other is original from your NukiBLE Library and example.

Thanks

Sven

If the UUID is detected, the pairing process should at least start. Can you see how far it gets?

[iranl]

Nuki Go is a 5th gen lock and needs

nukiLock.saveUltraPincode(YOURBLUETOOTHPINCODE, false);

set before initializing.

We haven't updated the example for 5th gen.

I also had already problems with the build. The reason is, that in the library.json of this project are old dependencies:

  "name": "NimBLE-Arduino",
  "version": "h2zero/NimBLE-Arduino @ ^1.4.0"

I had to override the references to the h2zero/NimBLE-Arduino @ 2.3.6 in my main project to solve it. Maybe the library.json can be updated?
