Problem after doing DFU over BLE.

[Vibhor]

Does doing DFU again and again on same controller can cause misbehavior of code? I am using BLE + UART + EEPROM in my code and sometimes I face the issue with UART event handler.  Normally if I use STlink to load the softdevice and application then everything works fine.

Hi,

It should not be a problem to perform DFU multiple times on the same controller. What is the issue you are facing in the UART event handler? Are you getting an UART error event  (error conditions)?
