Setting up Multitech Conduit Gateway for TTN

That's just data being received that might or might not be a valid packet. Stat: 7 actually is a CRC error (valid packets have stat 5) so no valid data has been received.

Packets with CRC errors are (rightly) not forwarded.

For TTN you need to use the instructions to make it a forwarder (step 3 in robbos message). The MultiTech software does not allow multiple servers so you will not be able to use the network server on the device. (If you want send to multiple servers, check my message [70] to get the poly_packet_forwarder, the package contains a valid example config for use in the EU)

You got it, the gateway will not receive packets it is sending so you need a node to receive data.

A sample EU config for the MultiTech software:

{
"SX1301_conf" : 
{
	"chan_FSK" : 
	{
		"bandwidth" : 250000,
		"datarate" : 50000,
		"enable" : true,
		"freq_deviation" : 25000,
		"if" : 100000,
		"radio" : 0
	},
	"chan_Lora_std" : 
	{
		"bandwidth" : 250000,
		"enable" : true,
		"if" : -200000,
		"radio" : 0,
		"spread_factor" : 7
	},
	"chan_multiSF_0" : 
	{
		"enable" : true,
		"if" : -400000,
		"radio" : 0
	},
	"chan_multiSF_1" : 
	{
		"enable" : true,
		"if" : -200000,
		"radio" : 0
	},
	"chan_multiSF_2" : 
	{
		"enable" : true,
		"if" : 0,
		"radio" : 0
	},
	"chan_multiSF_3" : 
	{
		"enable" : true,
		"if" : -400000,
		"radio" : 1
	},
	"chan_multiSF_4" : 
	{
		"enable" : true,
		"if" : -200000,
		"radio" : 1
	},
	"chan_multiSF_5" : 
	{
		"enable" : true,
		"if" : 0,
		"radio" : 1
	},
	"chan_multiSF_6" : 
	{
		"enable" : true,
		"if" : 200000,
		"radio" : 1
	},
	"chan_multiSF_7" : 
	{
		"enable" : true,
		"if" : 400000,
		"radio" : 1
	},
	"radio_0" : 
	{
		"enable" : true,
		"freq" : 868500000
	},
	"radio_1" : 
	{
		"enable" : true,
		"freq" : 869500000
	}
},
"gateway_conf" : 
{
	"forward_crc_disabled" : true,
	"forward_crc_error" : false,
	"forward_crc_valid" : true,
	"gateway_ID" : "<YOUR ID HERE>",
	"keepalive_interval" : 12,
	"push_timeout_ms" : 120,
	"serv_port_down" : 1700,
	"serv_port_up" : 1700,
	"server_address" : "54.229.214.112",
	"stat_interval" : 20,
	"synch_word" : 52
}
}

A valid config is actually generated by lora-network-server in /var/run/lora (apart from the server address and ports) if you start it with the configuration for EU as described on the MultiTech Website (steps 4-7)
