Hi,
I've a esp32-wroom-32D DevKit and I've followed the guide step-by-step, but "make flash" goes into error.

Code: Select all

Hi,
I guess this document will be helpful

Hi

The commit you mention to checkout 7fa98593bc179ea50a1bc8244d5b94bac59c9a10 in the https://github.com/espressif/esp32-at.git repository doesn not exist anymore. Is there another way to get the ESP 32 AT source code ?

Thanks.
