AT commands for ESP32 BLE to my Android ?

[ChrisJ7903]

I'm trying to work out the right sequence of AT commands to initialise BLE on my Sparkfun Micromod ESP32 Function Board (https://www.sparkfun.com/products/18430) that uses the ESP32-WROOM-32E. Hoping for expert guidance after trying many, many AT sequences with minimal progress success

If I enter this sequence after power up:
AT+BLEINIT=2
AT+BLEADVDATAEX="ESP32_XX1","02E5","123456789A",1

then ESP32_XX1 appears in the "Pair New Device" list on my Andoid Pixel 6, but when I select it nothing happens.

What other AT commands do I need to get them to pair / bond / communiate over BLE?

TIA

PS: Also previously I used AT+CWMODE=0 to turn WiFi off.
