Is there a way to send battery level using HFP? esp-adf/examples/get-started/pipeline_a2dp_sink_and_hfp

Hi,

I'm trying to connect smartphone with esp32 using this example https://github.com/espressif/esp-adf/tr ... nk_and_hfp. Is there a way to send the battery level of esp32 to smartphone? My headphones can do such a thing, so I think it is an option of HFP

Thanks
