Unable to setup esp AT commands bin

Postby wnoliveira » Wed Feb 06, 2019 6:54 pm

Hi all.

I am trying yo setup the at-commands module by flashing the esp-at.bin into the esp32 flash. However, I've trie to follow all the instructions on AT commands PDF and also some videos, but nothing works yet.

In the last AT version (https://www.espressif.com/en/support/download/at - V1.13) the avaiable bin files are:
-> at_customize;
-> blank;
-> esp-at;
-> factory;
-> partitions_at;
-> phy_init_data.

Which files I must download to esp, and in what address?

If someone can explain, I will be very aprecciated :D .

Regards.

Have you looked at section 1.2 of the AT documentation?

The flashing addresses are in /ESP32_AT_BIN/download.config.

Ok, I didn't notice that. That helps me a lot!

I successfully downloaded the binaries, as you can see in the module's response in my serial monitor:

However, the module doesn't answer the "AT"+CR+LF echo test. The initialization is correct?

Hi all.

Problem solved :D

The default serial for AT commands are not the same that show logs and download the bin. There is another serial for that.

All is working fine now.

Thanks a lot for the help.

Hi guys. It's basically open the flash addresses in /ESP32_AT_BIN/download.config (open this as a text file). After, be careful to use serial 2 to send and receive AT commands, not the main serial (those standard for dev kits).
