Yesterday we run a 7 hour test to check if everything works fine with the main board. We were at the same point excited and disappointed about the results: the hardware works without problems (wich was the main goal), but the station wasn’t able to upload data 8 times for about 15 minutes each.

We are putting all our efforts to solve that problem.

We made 3 hypothesis:

• The server could have been busy (but it could not have been for such a long time);
• There could have been problems in the serial communication between the ESP8266 and the ATMEGA328 (maybe because we used 115200 as baudrate)
• There could also have been problems between the ESP8266 and our modem, not allowing it to connect to the internet and so to perform the upload.
