Bluetooth for WiFi credentials

I made a simple data logger for a project and a few colleagues want to try it out. The plan is to ship it Have them access the ESP32 via bluetooth and put in their WiFi credentials to add to the list. Use it, then move it to another location.

Ideally, each successful use would save the credentials and add to the list Single use until changed is perfectly fine as well.

I have not used bluetooth and am looking for recommendations.

you can use SoftAP for WiFi provisioning. there are several libraries which implement it
