Flashing BLYST Nano with IDAP-Link using CoolTerm

The IDAP-Link has a special mode that allows flashing the nRF5x series via the COM port with a terminal program that support sending raw text files such as the CoolTerm. It is especially useful when you need to flash the nRF5x on a computer that does not have all the IDAP software installed. Here is how to use that mode. We using CoolTerm for this tutorial because it supports Windows, Linux & OSX.


This method only flashes one hex file. It mean that it could not flash Softdevice + App + DFu like the IDAPnRFProg program. You’ll need in this case to use Nordic mergehex utility to prepack into a single hex file for this.


Please note that you may see 5000000 buad on some screenshot. The screenshots were taken during development at that baudrate. The really baurate that work for this feature is 4000000.

I hope you’ll enjoy this feature.
