I pay 50$ (USA dolars) for writing a simple application (technology demonstrator) that will work on ESP32-LyraT 4.3
ADF 2.0 and IDF4.x required.

I want connect Headphone in HFP Hands-Free Unit mode (Speaker + Microphone) to ESP32-LyraT 4.3 working in HFP Hands-Free Audio Gateway mode and transmit 2 way audio (similar to 2 way intercom):

Microphone (on ESP32-LyraT 4.3) -> Audiocodec (i2s) -> ESP32 HFP AP application -> Bluetoth Headphone Speaker
and
Speaker (connected to ESP32-LyraT 4.3) <- Audiocodec (i2s) <- ESP32 HFP AP application <- Bluetoth Microphone in Headphone/
Microphone and Speaker work simultaneously. Echo cancelation is required.

Time to finish program: 2 weeks.
Please contact with me before starting programming: tcm3105___AT___o2.pl (replace ___AT___ by @)
