After updating to 5.3.0 the BluetoothSerial register_callback is not working as before. It generates the following error: ```error: no matching function for call to 'BluetoothSerial::register_callback(void (&)(esp_spp_cb_event_t, esp_spp_cb_param_t*))'``` I do not know if it is an actual error or there is something that has been updated. Using the previous version 5.2.0 it works correctly as before. Hope this help! Thanks a lot for your support!
