I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
Hi,
I use two evk board to connected and test the uart serialization sample(ble_s110_serialization), one is ble_app_hrs and one is ble_app_connectivity. But I have one...
I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hi,
I have created a custom PCB that more or less follows the Nordic SmartBeacon design: Beacon_V2.pdf
Instead of BAL-NRF01D3 I used the BALF-NRF01D3 as this is supposed...
