I’m using BC127 v7.1 in a proof of concept as companion for bleutooth communication.
After a while (weeks of use in AGHFP, connection and pairing) the module ‘fries’.
A boot UART trame is outgoing evry 200ms with frame error on unwanted baudrate (like 38400b Vs 9600b expected).
I didn’t recieve the official boot trame, the module didn’t execute reset or restore command.
The only way i found to unlock the product is replace the BC127…
I will try the [https://www.digikey.fr/product-detail/fr/qualcomm/DK-USB-SPI-10225-1A/DK-USB-SPI-10225-1A-ND/5269739](http://KIT SPI PROGRAMMER) to save my module
My Hw is quite simple
- The power is stable from 3V3 LDO.
- The VREGEN is floating, as eval board.
Thanks for your help,
