what is the max BLE pin character size?

Postby societyofrobots » Sat Oct 10, 2020 9:20 pm

I have a program that works great using a 6 character pin for BLE on ESP32.

However, BLE won't connect if I use a pin greater than 6 characters. The BLE standard should handle up to 16 characters.

My code seems correct, so perhaps its the hardware. But I can't find any documentation on this.

Does anyone know what the max pin character size is for BLE on the ESP32?
