Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...

Hi,
I am new to nRF5x BLE devices.
I need to create a project and would like you to help me out.
I need to connect two nRF51822 devices. If one of the devices goes...
hi dear officers
since the datasheet states that value 1 stand for connected, does it mean this pin is active-low.
in order to physically reset the device, could i connect...
I have tried ble_app_uart_c project in SDk 9 , SDK 10 or SDK11 , but they have the same problem.
Problem is that slave(SDk 9,ble_app_uart) can send data to master(by terminal...
