please help to confirm the ESD grade of nordic SOC. i can't find all the parameters(HBM, CDM,MM) in the datasheet, only HBM in 24LE1, and only HBM&CDM in nRF51822.
I'm trying the ble_app_hrs example on a custom nRF51822 board with s110 6.0.0 softdevice.
Debugging in Keil, the firmware runs fine up to ble_stack_init(). Within ble_stack_init...
Hi All!
In all exsamples in function "ble_evt_dispatch" we have different order to call sub functions.
Most functions to call is:
