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!
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...
Is it the only way to call a function on a read characteristic to make a read request and then inside on_ble_event call the function?
Is this the right way?
Hi
in the communication with an SPI peripheral device, a communication cycle might take up to 5 ms.
It is implemented as a blocking function, meaning that app_sched_execute...
Hi all! Several weeks I've tryed to implement code for my wireless temperature sensor based on nrf24le1 and ds18b20. In datasheet said that in memory retention mode the power...

Hi Nordic,
I have an application that perfectly runs in the nrf51DK but that does not work in my custom board. In my custom board everything else works (i2c, leds lighting...
I understand that in order to trigger bonding procedure you need to read/write a secure characteristic.
I am using the nRF Connect application on IPhone and trying to see...
Hi all,
I need to take samples of a period of two periodic signals and made some DSP processing with both signals.
I need at least 64 to 128 samples per signals.
