AT+GMR
AT version:3.2.0.0(s-ec2dec2 - ESP32 - Jul 28 2023 07:05:28)
SDK version:v5.0.2-376-g24b9d38a24-dirty
compile time(5c1d4b6):Jun 7 2024 15:43:17
Bin version:v4.0.0.0(WROOM-32)

OK

ESP-AT Firmware Source

1. Clone the v3.2.0.0 branch as recommended for the ESP32-WROOM module
2. Modify the SDK config to enable Bluetooth Classic and BT SPP
3. Not required, but change the binary version to show it is different to the branch configuration
4. Build and install using the factory binary

Hardware Information

ESP32-WROOM32(E)

Power Supply used

USB

What is the expected behavior?

When multiple pairings are present, and they are requested using AT+BTENCDEV? each pairing response is provided on a new line, for example:

AT+BTENCDEV?`
AT+BTENCDEV?
+BTENCDEV:0,"00:07:80:02:47:00"
+BTENCDEV:1,"90:38:0c:ed:67:02"
OK

What is the actual behavior?

AT+BTENCDEV?
AT+BTENCDEV?
+BTENCDEV:0,"00:07:80:02:47:00"+BTENCDEV:1,"90:38:0c:ed:67:02"
OK

Probability of recurrence

100% repeatable

Steps to reproduce

1. Follow the guide here on how to connect two ESP32 modules. Perform this using identical software.
2. Do this twice to make sure there are two different pairings
3. Send AT+BTENCDEV? to request the pairing list

I have attempted to test this using the latest release of v3.4.0.0 however it does not build successfully with BT Classic SPP enabled for the ESP32-WROOM module (#848)

Thank you very much for raising this issue. Yes, AT does indeed have this problem at the moment. We have replicated this issue locally and will soon internally synchronize the fix for this issue to the master branch. Thanks again.

Thank you for reviewing this item, do you have a timescale when this will be pushed to a suitable release branch for the ESP32? Master (and v4 and above) is not recommended for the ESP32 module.
