Constant Tone Extension / ESP32C61.

[pawel.cern]

Hi,

I am trying to use CTE feature. There are two example programs - periodic advertisement and periodic sync with CTE. Both work fine on ESP32H2. Unfortunatelly on ESP32C61 bogus IQ samples are returned - all I/Q values are -128.

Do you know where the bug is? Software, or hardware? I am trying to run demos mentioned on Espressif ESP32-C61-DEVKITC-1. Chip revision is 1.0.

I see no response from Espressif staff, so I decided to do some investigation by myself. Apparently it seems ESP32C61 and ESP32C5 have very similar BLE IP cores (likely the same). I copied static library libble_app.a from C5 directory to C61. And it seems the project works now. Position calculation based on IQ samples gives correct results.

Because of that I am kindly asking you to correct ESP-IDF, as it is software related problem.
