[SIM800] Looping with ERROR AT+CIPRXGET=2,1,63 #69

Closed widoyo closed 6 years ago

widoyo commented 7 years ago

I have successfully HTTP Post to web server every 5 minutes with SIM800L. I put code client.stop(); modem.gprsDisconnect();

after doing HTTP Post. Unfortunatelly, sometime I got my system lock up with message: ERROR AT+CIPRXGET=2,1,63 repeated until I reset my CPU.

How best practices if I want to POST data every 5 minutes? Thank you

Please try the latest release of the library, reopen if still have issues.

Good day,

I am using v0.3.3 of the library and I am experiencing the same problem as @widoyo . Any idea why this happens? Any workaround?

I'm at a point where I want to add a 555 Timer to reset if stuck for too long....

I get it too. The code was working at one point. I'm testing with SIM800L module using Wemos 8266 cpu. Maybe it's related to a race condition with reading the headers back from the server, or parsing on a character that isn't returned? I've tried:

The issue seems to consistently stop at the end (or second line?) of reading the server headers.

... previous lines removed...
