annotate Discovery/Src/tComm.c @ 400:7bcbbaa42cbf ImproveBluetooth
Added retry through power off/on cycle:
During tests sometime (<10%) the initialization of the module failed which was visible due to a deactivated Bluetooth option. Manual activation was always successfull. To improve the startup behavior a retry by using a module power off / on cycle has been added
