BLE advertising fails with `Cmd Disallowed` on ESP32-S3

[piotrkowalczuk]

Hi! Hitting a BLE init issue trying to run light_wifi.rs on ESP32-S3 with Bluedroid, advertising never starts even though Matter stack initialises cleanly and generates a QR code.

Tried (no effect):

• PR BLE - fix several bugs and rename a few things for extra clarity #27 BLE fixes (confirmed in build)
• Workaround from espressif/esp-idf#6418 - calling esp_ble_gap_set_rand_addr() before run_coex
• Minimal upstream sdkconfig.defaults (matches CI config) vs esp-matter-style - same error

Looks like the Bluedroid BLE initialization code for ESP-IDF 5.5.x and maybe later has a bug. BTW, this does not happen with the c6, so it might be s3 specific.

Try putting an earlier ESP-IDF here:

esp-idf-matter/.cargo/config.toml

Line 17 in a8a1b98

ESP_IDF_VERSION = "v5.5.3"

For me, it did work with "v5.4.3" and "v5.3.3"

[piotrkowalczuk]

Works with v5.4.3 thanks @ivmarkov.
