    Hi Fernando,
    We integrated yesterday in field conditions – it works. We put a Yagi antenna on the mDot – covered circa 5kms GW to GW (868MHz) in cross terrain at around -115db. MDOt should be in OTAA mode. If there is no data from nodes to be retranslated, mDot sends one join frame, remote GW acknowledges and nothing more happens. So we induced a “handshake” from Nodered – dummy data injected periodically (10mins or more) from mDot to remote GW, to monitor the join.

    Good luck.

    Hi Fernando,

    We managed to solve our problem with a work-around. It is not possible to associate one gateway to the other gateway thru the Lora cards. So we have following setup:
    – Gateway 1 receives messages from nodes, processes data with Node-red.
    – On USB Host of GW1 we put mDot on micro dev kit, in COMMAND mode
    – We send processed payload in Node red to Serial out flow, with a flag/index according to EUI of respective node, combined with AT+SEND command.
    – On GW2 the mDot is associated as a node
    – GW2 receives frame from GW1 thru the mDot, we further process/unpack with node-red to get our actual payload and feed it further to the PLC.

    Both GWs are in NS mode. For some reason we could not get the mDot to do the job in Serial mode, but serial comm is a pain by itself. It is a bit of a trouble until you find out on which port the mDot appears, in our case it was on XRUSB04.

    Good luck.

    Hi Lorenzo,

    File flows.json, located in \var\config\app\install\development should be copied to \home\root\.node-red

    Hi Jeff,
    Yes, it’s enabled, running and a flow is logging data. At restart, flow starts working after manual start of Node Red.

    Thanks Jeff.

    I’ll try, however it might be a case that the conduit may not accept upgrade nodes vers. higher than 0.10.X, due to instruction set.
