Hello,
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...
Because of the power-saving support, I want to disable the UART before Call the sd_app_evt_wait().
I referred to two following sites to know the procedure of the case....
I'm working with a nrf51422/s110 dev kit on which I downloaded the Heart rate Monitoring sample project. On my PC, using a s130 dongle, I connect the device and wrote some...
Hello,
I would like to know about the possibility of programming the nrf51822 with a Keil ULINK-ME Debug Adapter (or, if necessary, Keil ULINKpro) instead of the recommended...
