Struggling with A2DP_sink example

[chesham71]

This is my first foray into the ESP32. I am trying to build a bluetooth speaker and so the ESP32 looks perfect.

I have done

Code: Select all

make flash monitor

on the example provided in the esp-idf/examples/bluetooth/a2dp_sink, it uploads, and appears to run, but I can't see the device on my phone. I'm using nRF connect app by Nordic Semiconductors on android. Other bluetooth devices show up so it seems that the ESP32 is not available for discovery.
The output from the monitor is:

Code: Select all

I'm sure I'm doing/not doing something really simple here. If anyone has any tips to get me up and running that would be very much appreciated.
