Is It possible to modify an AT command? CIPSEND

Postby arturo12131 » Thu Aug 04, 2022 3:32 pm

Hi, I want to modify (or re-implement in a different command) the AT command "CIPSEND" since the maximum bytes to send is 2048 and I need it to be 8192 at least. How can I do that? Is any source code for that command that maybe I could change and implement?
Thanks in advance.

Hi,
Which firmware are you using, the AT+CIPSEND command (https://docs.espressif.com/projects/esp ... rough-mode) <length> for ESP32 AT and ESP32C3 AT has increased to 8192.

Hi, I'm using Esp-wroom-02 (esp8266).
Sdk ver: 2.2.1
At ver: 1.6.2
Compiled on 2018

Thanks

it seems you are using the deprecated NONOS-AT, you can refer to https://github.com/espressif/ESP8266_NO ... ain.c#L147, and define your CIPSEND command. This might be a little bit difficult for beginners.

Or consider to use ESP32-C2, ESP32-C3, ESP32 chip, which AT+CIPSEND already support 8192 bytes. also has AT+CIPSENDL support to send long data in Paraller, more details are in https://docs.espressif.com/projects/esp ... #cmd-sendl
