Hi,
I'm having trouble maintaining a connection with the PROC module (CYBLE-022001) mounted on the board I'm bringing up. I'm running BLE UART example code (Server code on the PROC and Client on a CY-SMART board).
The two devices continuously connect then disconnect - typically after just a few seconds.
The same code (slightly different target) runs just fine on the cypress pioneer kit.
I checked power-supply noise on the 3.3V rail (it's less than 40mV pk-pk). I'm using standard BLM21P331 ferrites. XRES is noise-free and high. I don't see any requirement to pull-up or pull-down other signals.
Any suggestions?

For some unknown reason it just started working. Maintained connection for full 12 hours until power-down. I have no clue what changed. There have been no software or hardware changes. I'll update this thread if there are any further developments.
