Hi,

It is planned in near future to made ESP32 support TCP passive mode as ESP8266 does? It would be a very big advantage four our company and I think for others too. ESP32 has a lot of free ram and storing received data in ESP's buffer would help a lot with receiving big files (a few 10KBs) (eg: firmware file or an image, etc.) with small MCUs. In this case the small MCU could do whathever it's task and read & parse TCP message from ESP when already every critical task finished.

I'm just curious that this feature will come to ESP32 too in near future, or we should find another solution for this problem.

Thanks.

E: Is it planned to made ESP8266's TCP passive mode buffer configurable? eg: Increasing it to 2-10KB.

Hi,

We are working on the ESP32 AT TCP passive mode now, it will be provided on the GitHub in the near future.

But sorry that due to the memory limitation, we may not add more buffer for the ESP8266 AT passive mode.

Thanks.

Thanks for quick reply, this is awesome!

Anyway for ESP32, buffer size will be configurable during build/via AT command or it will be hard coded?

E: In near future there is a plan to add a command to read out MCU temperature? We would very appreciate it.
