MaixDock WIFI Module delay / freezess

Hi, I’m programming a infinite loop to send data to an HTTP server, it never stops and makes 10 request / second.

I’m working with a custom made code using AT commands with the ESP8285, I’m working with Kendryte standalone SDK , every thing works fine and very fast (I’m working with 2.5Mbps of speed) , but randomly the programm freezes waiting for a “SEND OK” message sent by the ESP8285, the delay caused by this issue takes 15 seconds or 70seconds.

I’ve search the web and found that many programmers had the same problems with the ESP8285, and in the web page/bbs of the manufacture they never helped the programmers.

¿Do you have any clue of what is going on?
