I am trying to get the BLE example "examples/bluetooth/nimble/bleprph" running on a ESP32c6. Background is that in my project I need extended advertising (manufacturer data). When I compile and run the example with no configuration changed (extended advertising is on by default), I can't find the device on my phone (using nRF Connect app). Just as an experiment, I disabled extended advertising. Then, the device is visible on my phone.
Bellow is the output from the monitor (I had to add a vTaskDelay(500 / portTICK_PERIOD_MS); as the very first statement in app_main to get over Waiting for the device to reconnect in the monitor. See https://esp32.com/viewtopic.php?t=21505):

Has anyone been able to get the extended advertising running? Am I missing something?
