BLE UART reboot crash

[Mark]

Hi,

Thanks for the library first!

I noticed while using the commands via Nordic Connect etc that the ESP32 thing would occasionally core error and reboot.

Guru Meditation Error: Core  0 panic'ed (Unhandled debug exception)

I also wondered if you were available for contract work? I have a project to connect an ESP32 to a Particle P1, UART bridge from smartphone app so that WiFi setup details can be provided to the P1, and for basic device status (256 char status string) reading and for basic config set (256 char string). Many thanks!

Can you please provide the CORE Trace via
make menuconfig
Component config ---> ESP32-specific ---> Core dump destination (UART)
Component config ---> ESP32-specific ---> Panic handler behaviour (Print registers and halt)

then copy all line between (!) the head/foot to a core.txt and run like this:
python $IDF_PATH/components/espcoredump/espcoredump.py info_corefile -t b64 -c core.txt build/ble_nus.elf

Sorry no contract work now.
