Device disconnects from Wifi after new round is started, so no MQTT message can be sent

[vrjpellenz]

The Problem

The symptom was that only a fraction of the MQTT messages are sent out from the device. The logfile states that the connection to the Wifi is lost frequently after a new round is started. When the round is finished and the device tries to send out the read value, the Wifi connection is still down and the message is not sent. Shortly after the round is completed the connection is re-established. See log below.

Your signal strength is quite bad..

Also ensure proper power supply.
For testing purpose try a stronger power supply and get the device closer to the AP
