'The selected analog pin will be acquired by the ADC when it is enabled through...
Hi !
According to application requirement, we need to minimize the RSSI variance of the BLE beacon as small as possible. Our RF team has tried to minimize the 37/38/39...
Hi,
I am trying to bond the nrf51-DK with the android smartphone. I want to display the passkey to the user which would be done using BLE_GAP_IO_DISPLAY_ONLY. After which...
