ESP BLE mesh transmit power

[svelte]

Hi ESP32 Forum members,

Does anyone know how to increase the transmit power for BLE advertising when used in a mesh. Having looked at
viewtopic.php?t=21011
I used the same procedure to set the esp_ble_gap_ext_adv_params_t.tx_power to the appropriate ESP_PWR_LVL_P9 power but it raises runtime error with the internal BLE mesh advertisements initialization.

Any suggestions, on how to proceed?

Thanks in advance
