example_spp_acceptor_demo won't start under debug

[tim8656]

Hi

I am using esp-idf-v4.4, platformio and VS Code. I am using an AZ Delivery ESP32DevKitCV2 and ESP-Prog debug board.

I have built example_spp_initiator and it runs successfully under the debugger and my Serial Bluetooth Terminal app can see it.

Using the same hardware, I can build the companion acceptor program and upload it to the ESP board.

However, when I try to run the program under the debugger, despite placing a breakpoint on the first line on main(), I am getting the following:

esp32.cpu1: Debug controller was reset.
esp32.cpu1: Core was reset.
esp32.cpu1: Target halted, PC=0x40000400, debug_reason=00000000
Temporary breakpoint 1 at 0x400d278c: file src/main.c, line 168.
PlatformIO: Initialization completed
PlatformIO: Resume the execution to `debug_init_break = tbreak app_main`
PlatformIO: More configuration options -> https://bit.ly/pio-debug
Note: automatically using hardware breakpoints for read-only addresses.

Where do I start looking?
