communication test

Today, my colleagues and I went to the new sensor site to inspect the civil work preparation. We also take this opportunity to test the communication between the sensor site and the headquarters. Several days ago, EMT said that they had already tested the link but today we found that data cannot be transmitted successfully. EMT explained that in their previous test, they only pinged the remote server (i.e. testing the "network" connection) but no test on serial communication was carried out. Devil is in the detail! No detailed test was made!!!

Fortunately, the main purpose of this trip is site inspection. Installation of sensor will be carried out three weeks later and therefore we still have time to fix the communication problem.
