V1 has underside connection pads for the never released ESP3212 module. V2 has underside connection pads for the ESP-WROOM-32/ESP-32S module. Also, V2 development board pinout differs from V1 So if you have v2 and it says esp-32s on the bottom then it will work. Sorry for confusion. http://aitendo3...

V1 Won't work

But you could still use it as a programmer just put esp-32s on a different breakout board.

You can interrupt on a # of received chars or a specific command char

No esp-32s is an ai-thinker module. Ebox module is called esp32-bit

I meant the ESP32-T dev board can work with the ebox maker module.

Yes esp-3212 is discontinued and its footprint is not compatible with esp-32s/esp-wroom32. But supposedly it can work with ebox maker module.

I knew you could do it!

There is some effort on BTStack but it is dual license.

Yes there are kconfig options to reduce BT code and ram size. But also did you make the ota partitions bigger?

Oh OK for IDF just look at the examples https://github.com/espressif/esp-idf/tr ... r/examples and docs http://esp-idf.readthedocs.io/en/latest/
