I’ve been having some issues getting a Multitech AEP Conduit (MTCDT-LEU1-247A-915) relaying data to TTN. The gateway shows join requests and accepts, however will not progress to the data transaction. I am using an xDot as my end device, and am looking at working with AS923 due to band plan changes in Australia (using frequency sub-band 2). The device does connect to local public network, and data flows as expected. This has led me to believe that it is this gateway I am using that is causing the issues. The conduit is connected to the internet using a cellular back haul.
Upon viewing the log output for the packet forwarder, the error that occurs within the gateway is : Cannot send packet, channel is busy (LBT). I have followed the steps mentioned in this forum discussion (Multilink Conduit install problems), with the FPGA updated to the required version successfully. I have also changed the global config to set LBT to false, along with making sure the TTN latest is not pulled and updated at packet forwarder run time. I have tried various settings and config files, but there has been no luck in successfully getting data through.
Any help or guidance in the right direction will be greatly appreciated.
