Helium Hotspot getting InvalidPacketType(7) on decode

Issue: I’m setting up a Helium Data-Only-Hotspot with a RPi2 + RAK2245, following the instructions here: Data Only Hotspot Setup with RAK Concentrator + Raspberry Pi | Helium Documentation

I can successfully send data from a test sensor and it appears in the helium console, however I’m not seeing any other traffic (i.e. other than mine) going through my hotspot. I also see a lot of entries like this in syslog:
“helium_gateway[417]: ignoring push_data: Decode(LoraWan(InvalidPacketType(7))), module: gateway”

Other Helium hotspots in my area seem to transmit a decent volume of traffic and I have a good placement of an outdoor antenna. I’m thinking something is not configured correctly.

Setup: RPi2 (latest Raspbian OS Lite, upgraded) + RAK2245 (latest rak_common_for_gateway)

Server: Helium
