I was also able to identify the meaning of the http result codes -1 and -11 which were returned by the POST function: #define HTTPC_ERROR_CONNECTION_REFUSED (-1) #define HTTPC_ERROR_READ_TIMEOU...

Hi ESP_Angus, thanks for your feedback! Following your recommendation I swapped only the logic boards of both units (the ESP32 with PCB antenna now sits in the sealed enclosure). Will keep it running for as long as it is required to gather some meaningful data and will keep you updated. Please see b...

Hi tachin, unfortunately I was not able to solve this so far. Kept both systems running in parallel for some more days and the symptoms are still there: data integrity monitoring 2020-02-09.jpg By the way, I noticed that the phases of bad connection mostly start around 0:00 and then last for a coupl...
