Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
Hi,
As discussed here a way to advertise each 20msec is changing the mode to BLE_GAP_ADV_TYPE_ADV_IND. This is a connectable mode and assume we do not want a connection...

Our system will awake from an external accelerometer interrupt, so I would need a code fragment which shuts down S110 soft device (and radio of course) and also all the nRF51822...
Hi,
I'm trying to test a new nrf51 board using the s130 softdevice and the ble_app_hrs_130 example. However, the program seems to hang in the ble_stack_init function (code...
