So far I have made a successful program that utilizes BLE to send and receive radio signals in Kiel. But I have only been testing this program by using the provided Master Control Panel host. I have done a bit of research on Androids, and which models can support BLE, but I've found no definitive evidence one way or another if BLE is a firmware or a hardware upgrade.
So my question is this:
Which phones will work with the Nordic chip through BLE, or could work with a software update? And do you know of any good SDKs or APIs to facilitate my next step of testing?
Thanks in advance!
