Multilink Conduit install problems


(Jac Kersing) #21

It should. However, somehow it seems the packet forwarder does not recognize LBT being available. Hard for me to test as I’ve got EU868 hardware which does not support LBT. (LBT minimal frequency is 915MHz according to MultiTech documentation)

No need if you use my prebuild package (or source tree). It already includes the patches.

No, once you used the installer you should not use this page.
BTW, there is nothing to manage as the settings on that page are all included in the TTN configuration.

@kersin Thanks Jac, I will try to open a ticket to Multitech.

Hi @kersing

After chatting with my MultiTech local reseller (Melvin).
He advised to upgrade the FGPA to v33.

Stop any processes that try to access the MTAC-LORA card. For example, the LoRa Network Server and the LoRa Packet Forwarder or other third-party packet forwarders (e.g. Loriot, TTN, Actility, Senet, Orbiwise, etc.).
Navigate to /usr/lib/mts-flash-binaries and run:
mts-fpga-loader -i mtcdt-fpga-v33.hex

The file mtcdt-fpga-v33.hex is part of the firmware 1.4.16.
It is working now with LBT on.

Nice find @brice. I’ll also test a gateway with that firmware version shortly.


(Jac Kersing) #25

Excellent news. Thank you for researching this. :smile:


(Andrew Maggio) #26

I’ve tested on an IP67 Conduit (LEU1-266A). Upgrading the FPGA to v33 solved the LBT error. Thanks @brice for solving and @kersing for your wisdom.


(Andrew Maggio) #27

Apologies for reviving an old thread, but for completeness, v33 of the FPGA firmware broke downlinks for me. I’m leaving my gateways at v31 for now, until we feel the need to enable LBT.

I installed packet_forwarder for ttn on my multitech gateway as I follows guide ([https://www.thethingsnetwork.org/docs/gateways/multitech/aep.html])on here and tried to connect to ttn via multitech gateway.

then I have the same error before with lbt error as following log.

Can anyone see my log and advice me please.

You will need to disable LBT or load the v33 firmware onto the MTAC-LORA-H card.
