A "LoRa" ( Long Range ) wireless data link had already been used in a previous project to collect soil moisture data; but was not joined to a LoRa WAN network, in which nodes ( end-devices e.g. sensors ) are connected to gateways which then connect to the network server where the data from the end-device can be displayed and accessed by other applications for long-term storage and visualisation.
The public "TheThingsNetwork (TTN)" global IoT LoRaWAN network with the "Things Stack Community edition" server were used to test the possibility of connecting a node comprising a TTGO LoRa32v2 development board, before designing future projects with sensors. Only a short text message was to be sent; "TTGOLoRa32v2 node test".
The message was successfully received by a gateway 6kms away and forwarded to the server.
The upper image shows the experimental node in a temporary location by a window. The lower image is a partial screen capture of the live data on the server console.
