Wwhen I have the user code in place, if I connect to it or disconnect from it (depending on what user code is in there), it goes into a HardFault exception if the phone touches it.

Environment:

Usingng the SPBTLE-1S "postage stamp" on my own board [3v3 supply, external regulator from 12-400V, 100mA available], (using the programming/serial from a STM32F030 Nucleo board) and that works quite well (wish it supported more breakpoints!). I'm currently using the BlueNRG-1_2DK2.6.0 stack. I'm using the SPBTLE-1S as the only micro (like I said, super simple application).
