Welcome to the Official ESP32 forum!

[ESP_Admin]

We have closed the beta program for ESP32, and will be preparing to send out the demo boards.

H!

When do you think we´ll be able to buy the modules? and where can we do it?

Thanks!

I can see a few links to ESP32s on Aliexpress that seem to be available at this time. See this one link

I am Working on ESP32 Module , I have successfully downloaded .bin file through ESP Flash Downloader Tool .
However I am unable to get the responses of AT Commands .
It seems like , ESP32 module is not initialising successful .

""phy_init: failed to load RF calibration data (0x1102), falling back to full calibration<ESC>[0m<CR><LF>""
Error is received on Debug log .
Please help me to solve this issue .

I have attached the debug log of ESP32 Initialisation process .

This topic is no place for this. (Actually, this topic is pretty ancient in general; I'm locking it down.)
