I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...

Hello,
I cannot find an example in the current SDK on how to use APP_UART. I do not want to use app_uart_fifo because it has quite some overhead that I do not need. All...
I am using nRF5_SDK_11.0.0_89a8197 to test esb maximum throughput.
in the macro definition of NRF_ESB_CREATE_PAYLOAD,

On the nRF51, there are 5 OVERRIDE registers (0-4) in the radio module.
What do those registers do and when should they be used? The FRM was not clear about them.
From what I can see the scenario where you have a serialized app running from a separate CPU and how to do firmware update on that is not discussed anywhere on the Nordic...

I have a code that continuously toggles a pin(I use nrf_drv of gpiote+ppi+timer2 for this purpose and interrupt time = 30usec). I have basically taken the...
I know the things like the TWI allow you to send additional data when you instantiate a transacation. Is there any way to do a similar thing with UART?
I'd like to pass...
