MKR WAN 1310 - Dual-Channel Gateway Connectivity Issues (US915)

Hello,

I recently purchased an MKR WAN 1310 with a Dragino LPS8 Gateway. Both the 1310 and LPS8 are configured for US915. Dragino indicated the sub-ban frequency on the MKR should match that of the LPS8 and uncertain if the firmware for the CMWX1ZZABZ supports frequency bands appropriately.

Sample code under test is the 'FirstConfiguration' with US915, App Key and EUI Key generated from The Things Network.

Is anyone else having issues connecting to a dual-channel gateway with US frequencies?

Thanks
