I have an nRF52840 dongle that I am using to connect and read/write to a client unit. I have been able to use the nRF Connect Bluetooth Low Energy program to control the dongle, find my unit, connect to it, and successfully write to its characteristics.
I am now wanting to be able to do this same process, but using a C program. I have downloaded the nRF5 SDK 16.0.0 software, and the nRF BLE Driver 4.1.1 software folders, but there are so many files and directories in here that I'm not sure where to begin. Could someone point me in the direction of an example program I can use to emulate the functionality of the nRF Connect Bluetooth Low Energy program? Thanks!
