I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
Hello Everyone,
I am trying to use a display (through SPI) in a custom board with nRF51822 and SoftDevice S120. All works great as long as I call the SPI methods from main...
We have the HCI DFU working. The PC sends the new hex image (python script) via UART to nRF51822. Therefore, the bootloader code on the nRF51822 works. However, in the final...
Hi,
i'm using s130 central/peripheral. I want to send data from my central nrf51822 to my peripheral nrf51822.
I declare write function like this:

Hi guys. I have a nRF51822 reference design board which is based on low voltage mode circuitry (using 1.8V supply directly). However, my Segger Jlink (SWD) does not work while...
By default, S110 advertises in all three advertisement channels. I need to limit the advertisement channels, so that I can advertise on a single.
In a similar question...
I now this are basics. And I did this allready a few times, but in this project it simply wont work.
Maybe someone of you will find something, that is missing.
