i'm using a NUCLEO STM32WB55RG-D01 eval board.
BLE_HeartRateFreeRTOS sample and my test app were working fine.
after some time of development my test app i found
- my test app is still running ok doing some serial communication but
- BLE still advertises my device name but i'm no longer able to connect to device over BLE (connection timeout)
to check whether it's related with my test app i switched back to the (unchanged) sample app : BLE_HeartRateFreeRTOS : also there i still see it advertising but trying to connect always runs into timeout (same symptoms as with my app).
what migth be broken and why ? what can i do to check (and possibly fix) why it is failing now even with the unchanged sample apps .
other (non BLE) functionality is still running fine.
stepping in the debugger i see no trouble even the connection callback gets called when i try to connect ...
thx, peter
