AT commands in ESP32
Posted: Sat May 12, 2018 8:33 am
So, I tried to control my ESP32 over AT commands but I failed. Will tell you what I did and if anybody knows where the mistake might be tell me
1) Cloned official repository
2) loading the project to the ESP
As far as hardware is concerned I connected another one USB-UART adapter (other than the flashing one) to the appropriate PINS(sure of it).
Ubuntu sees it with no problem : /dev/ttyUSB0 & /dev/ttyUSB1
Then I run
From here after it is like I am not simply in AT mode and I just uploaded a usual application.
I cannot change port from my flashing ttyUSB0 to my AT-enabled ttyUSB1.
Cntrl+T-Cntrl+H does not give any new feedback for me to take advantage of.
Tip : Where the problem might be is that I omitted using properly ESP32_AT_BIN at http://www.espressif.com/en/support/download/at as https://www.espressif.com/sites/default ... les_en.pdf said (paragraph 1.2).
Actually I tried downloading it, but didn't know what to do with it.
Would you like more details, let me know. Waiting for your support !
* I also tried setting my IDF_PATH variable to /path_of_my_esp32-at_cloned_repository/esp-idf but still nothing
**I also watched https://www.youtube.com/watch?v=HBrEMIzm_uY ,which may seems to be outdated ??
***I also run steps 2, 3, 6 and 7(when it was needed) from https://github.com/espressif/esp32-at . Step 8 confused me a little. I assumed it just wanted me to change my IDF_PATH to the new path?
1) Cloned official repository
Code: Select all
git clone --recursive https://github.com/espressif/esp32-at.git
Code: Select all
make flash
Ubuntu sees it with no problem : /dev/ttyUSB0 & /dev/ttyUSB1
Then I run
Code: Select all
make monitor
I cannot change port from my flashing ttyUSB0 to my AT-enabled ttyUSB1.
