Hello all,
I'm stuck in the use of the UART.
I have used the code from the UART example and the UART application for iPhone. I'm using eclipse because I don't want to...
Hi,
i have some troubles with my software which i doesn't understand maybe some one with more microcontroller Experience cann tell me how to solve this Problem.
I have...

With the DFU sample from SDK v4.4.0.30888, I am unable to see the device in any host-side BLE monitoring utilities such as LightBlue (on Mac OS X) and our own custom BLE tools...
I need to transfer few kilobytes of data from slave device over BLE when requested from master device. I tough there is no file transfer profile in LE? What are the options...
Dear Nordic,
I know each sample has unique device address and stored in NRF_FICR->DEVICEADDR[0] and NRF_FICR->DEVICEADDR[1], and I think it has unique device UUID too....
In my ADC interrupt service routine (ADC_IRQHandler), I'd like to have a pointer available that I could use to carry some state from the main app thread to the IRQ handler...
Hi all
My nRF51822 has a incorrect LED signal, seems become a battery mode when I plug in a USB port.
The detail feature as below:
Incorrect device type in Micorsoft...
I'm looking at a BLE application using the nRF51822 where we need to send data maybe once every 10 minutes, so it seems like disconnecting in between sending messages will...
Hi,
im using nRF24L01+ to constantly transmit data and all working fine, but at some point SPI fails and the only returned values I get are 0x0F - doesnt matter which register...
