I'm calling ble_bondmngr_bonded_centrals_store in response to BLE_GAP_EVT_DISCONNECTED as is the case in plenty of sample code, but when ble_bondmngr_bonded_centrals_store...
Hi Guys,
I have managed to get the BLE DFU demo service working fine (dual bank) on nRF51822 EK. I use a Linux Python program ( bitbucket.org/.../nrf51_dfu_linux) (with...
what is the detection speed, when the beacon
enters into a wall unit area? With their 868 beacon they can
detect in 0,2 seconds. Is the nRF51x22 in sleep mode and does it...
