I'm looking for a sketch that implements either an AT command set, or HCI (Host Controller Interface) for the Nano 33 BLE.
OK I'll tell you. I am messing around with the idea of using this chip to emulate various protocols. Rather than buying fixed function devices. You know? They all do the same thing. Most of the time its just changing the command set. So far I have a command interpreter and about a dozen commands.
I disagree with that design decision (re needing to stop/start advertising) so in my code (which I will publish here eventually), when a setting is made, it will stop advertising for a millisecond in order to change the parameter (eg localName) then restart advertising. So it just changes.
