You can use the firmware from Adafruit for it (Bluefruit52): base it on this firmware: use a JLink segger to program the module and after that I can reprogram it using the UART, I like the Adafruit solution since they let you program it right from the Arduino IDE and that makes life very easy. I can reprogram the name that one sees in scanning for devices though, but one can set the 'local name' and even things like peripheral information from within your Arduino sketch.

Is it possible to hand solder this module? It looks like it might be a bit of a challenge...<br/><br/>

It is possible but I use solder paste and it requires skills if you want to bake it on a normal PCB adding wires to it is doable using a normal soldering iron I guess.

The nRF52832 module supports ANT protocol through loading S212 ANT SoftDevice or S332 Concurrent ANT/Bluetooth® Low Energy (BLE) SoftDevice. Can these softdevices be loaded onto this module so that it supports ANT?<br/><br/>
