When CONFIG_EXTERNAL_COEX_ENABLE is set to both ot_rcp and esp-thread-br config, connection to Wi-Fi using the CLI wifi connect -s my_ssid -p my_pass is failing. With coexistence disabled, the connection is successful.
If coexistence is enabled, but Wi-Fi connection initiated using the protocol_examples_common component, then the connection is succesfull (but it's expected since coexistence is only really enabled later in the code).

I'm using a custom board based on the Espressif ESP-Thread BR&Zigbee GW rev1.1. The wiring is slightly different though and I'm using pin 12, 13 and 14 of the ESP32-S3 for COEX_PRIORITY, COEX_REQUEST and COEX_GRANT respectively. It is configured as such in the sdkconfig of esp-thread-br :

#
# External coexist wire type and pin config
#
CONFIG_ESP_WIFI_EXTERNAL_COEXIST_ENABLE=y
CONFIG_EXTERNAL_COEX_ENABLE=y
CONFIG_EXTERNAL_COEX_WIRE_TYPE=2
CONFIG_EXTERNAL_COEX_REQUEST_PIN=13
CONFIG_EXTERNAL_COEX_GRANT_PIN=14
CONFIG_EXTERNAL_COEX_PRIORITY_PIN=12
# end of External coexist wire type and pin config

In the output log, one line is interesting :

I (14958) wifi:Set ps type: 0, coexist: 0

coexist is alway 0, wich or without CONFIG_EXTERNAL_COEX_ENABLE.

After boot and before issuing the wifi connect command, the state of the PTA pins are as follow :

  • WL_ACTIVE (grant) = LOW
  • BT_ACTIVE (request) = HIGH
  • BT_PRIORITY (priority)= LOW

During the command execution :

  • WL_ACTIVE (grant) = HIGH
  • BT_ACTIVE (request) = HIGH (no change)
  • BT_PRIORITY (priority)= LOW (no change)

After the command execution :

  • WL_ACTIVE (grant) = HIGH
  • BT_ACTIVE (request) = HIGH
  • BT_PRIORITY (priority)= LOW

If I disconnect BT_ACTIVE signal, the connection happen successfully. I guess the BT_ACTIVE default state should be low but it's not. Also when I start the thread border router, there is no activity on this pin. SO I suspect the issue might come from the RCP
(ESP32-H2) side.

I was using IDF v5.1.1 and the feature has been introduced in ot_rcp from IDF v5.1.2.
Adding the external coexistence initialization to the ot_task_worker after esp_openthread_init was sufficient to make it work.
