And another thread were people are asking for any help on this...
viewtopic.php?t=3178
Another request on github:
https://github.com/espressif/esp-idf/issues/626
This seems to indicate that a UART example might do in a pinch and in fact, there is such an example in the latest IDF:
https://github.com/espressif/esp-idf/bl ... art_demo.c
but this is not the bluedroid I am looking for. This seems to interface the UART periperal to a hci connection? HCI is not easy to do in windows like SPP or RFCOMM.
Ideas?
