I just realized i had not phrased my question properly. With a Xenon based product i wont be able to connect to the particle cloud since it has no WIFI. Lets say i have a BLE based code on either of the gen 3 devices (Xenon/argon), and i want to ensure that the code still works on this module. How do i upload the initial firmware on to the module, so that when i port my code from my xenon/argon on to this module it works. I am specifically referring to the following line.
The module comes with a blank chip - this is for people who are comfortable programming the chips themselves with a J-Link programmer and the Nordic SDK.
