Read Error Code from HTTP Post after "ERROR" feedback

[aphardt]

Hi

Im using "AT+HTTPCPOST" but it returns with "ERROR". How can i check what error code it is?

is there a "AT+????" API to get the error code?

Can you provide the version information of the firmware with the AT+GMR (https://docs.espressif.com/projects/esp ... nformation) command? And you can query whether the current version supports the AT+HTTPCPOST command through the AT+CMD? (https://docs.espressif.com/projects/esp ... t-firmware) command. You can also use AT+SYSLOG=1 (https://docs.espressif.com/projects/esp ... ode-prompt) to enable error code prompts

AT version:2.3.0.0-dev(s-fdd2ef7 - ESP32C3 - Nov 19 2021 07:49:55) SDK version:v4.3.1-480-g233dc30fb1 compile time(2b307bb):Dec 9 2021 15:46:09 Bin version:2.2.0(MINI-1)

I have the syslog enabled but still, there is no ERROR output other than the message "ERROR"

I just switched to this branch to test, the AT+HTTPCPOST command can work, if possible, you can provide the sequence of your AT+HTTPCPOST command
