General • basic networking with BT on pico 2 W

noob here. Tried to track this down but I can't find the answer.

I have an idea for a project using a pico 2 W. It will use wifi to connect to a time server somewhere.

I want a user to be able to configure some parameters at first run. SSID, pw, and some other info specific to the project. I want to do that config wirelessly, with a smartphone. I do not want the user to require plugging in to USB.

Is it possible to use BT to do that initial config? Once the pairing process is complete, how would I get the data into the pico? I imagine serving a web page and querying for the parameters, but it's unclear to me if that's possible over BT. Would I need an app on the phone?

I can imagine starting the pico in AP mode and connecting via wifi to do the config, then switching to client mode to do the time fetch. Seems klutzy, and once I am in client mode and connected to wifi, I can't talk to the pico without knowing its IP address, which will be assigned via DHCP from my wifi. If I can use BT as a dedicated channel I would prefer that.

Possible?
