OK

ESP-AT Firmware Source

latest release with Ethernet module on

Hardware Information

ESP32 WROOM 32E

Power Supply used

USB

What is the expected behavior?

AT+HTTPCPOST="",13,1,"Content-Type: application/json"

OK

+HTTPCPOST:117,
+HTTPCPOST:512,
+HTTPCPOST:512,
etc..
+HTTPCPOST:512,
SEND FAIL of SEND OK

What is the actual behavior?

After i send a AT+HTTPCPOST i get OK. but when follow up with the data the response i get
is the code of the error page but no SEND OK or SEND FAIL to indicate the transmission.
It's true that I get an error page, the place I sent it to had an issue but I would still expect a SEND FAIL

Probability of recurrence

in the case i describe, always

AT+SYSRAM?

AT+SYSRAM?
+SYSRAM:151152,144220
OK

Steps to reproduce

1. connect ethernet
2. Preset the URL
3. Preset header with a key
4. Send: AT+HTTPCPOST="",13,1,"Content-Type: application/json"
5. Receive: OK
6. Send the json data
7. Receive: +HTTPCPOST:512,
8. Did not receive SEND FAIL

AT command port output

AT+HTTPCPOST="",13,1,"Content-Type: application/json"

OK

>+HTTPCPOST:117,<data>
+HTTPCPOST:512,<data>
+HTTPCPOST:512,<data>
etc..
+HTTPCPOST:512,<data>
ready

@Daphne-HU Hi, could you please use latest master branch and enable more logs to see what happened:

• python build.py menuconfig -> Component config -> Log output -> Default log verbosity -> Debug
• python build.py menuconfig -> Component config -> AT -> Enable ESP-AT Debug
• python build.py menuconfig -> Component config -> AT -> Enable ESP-AT Debug -> Enable Network Debug
• (Disable BT to reduce bin size) python build.py menuconfig -> Component config -> Bluetooth -> Deselect

The AT log port output should give more logs.
