  After your point of me missing to flash the softdevice i tried the below steps and now the device is being detected over bluetooth. I was able to connect to the device over bluetooth, from mobile using the webide on chrome.

  There are 3 files created, a .hex file , a .elf file, and a .zip file.
  Any particular order these files have to be flashed?
  Any specific options to be passed for flashing?

  Hi,

  I have couple of Holyiot YJ-17095 modules based on nRF52832 for which i want to flash espruino.

  I have the espruino files on a Debian 10 VM and have copied the MDBT42Q.py file to MDBT42Q_CUSTOM.py and changed the console to EV_BLUETOOTH. The pin numbers are changed as per the module.

  The compile is successful. I copy the firmware to another linux laptop and flash the firmware using a ST-LINK V2 and openocd. i am able to flash the firmware.

  After the firmware flash and power reset of the module, the module is not discovered by bluetooth.
  Any pointers to where i may be wrong or missing some requied steps?

  Thanks in advance.
