Here a mBed code to send a hello world to TTN. [https://developer.mbed.org/users/ropu/code/mDot\_LoRa\_example\_TTN\_connect/](https://developer.mbed.org/users/ropu/code/mDot_LoRa_example_TTN_connect/) this should replace the terminal commands.

> [@robbo](#): > > Don’t forget to add your gateway EUI from the label on the bottom of your Conduit. Note that I used a fixed IP rather than croft.thethings.girovito.nl since I did not set up the Conduit for DNS. Good walk through @robbo. Just one clarification. The EUI in the gateway config should be the EUI of the MTAC-LORA accessory card instead of the Conduit. -Brandon ---

@brandon-multitech Thanks for the correction. I made the update. Is there a way to query the EUI from the command line? I must have used the wrong EUI but it still worked? ---

Hi all! You guys helped out a ton, especially the post from robbo was very valuable. Unfortunately, it’s not working yet. I don’t have an mDot yet, only the gateway. I’m simulating messages with mosquitto\_pub, and it seems like they’re being received (I see “Note: LoRa packet” in the packet forwarder log). However, nothing is forwarded to TTN, I get 0% ACK and (after sending some messages) a CRC\_FAIL of 100%. I used tcpdump to see that there is some UDP traffic going to TTN, once every 12 seconds or so, and a package coming back as well. So that’s good I suppose! A typical log entry: ``` ##### 2015-11-20 19:49:24 GMT ##### ### [UPSTREAM] ### # RF packets received by concentrator: 0 # CRC_OK: 0.00%, CRC_FAIL: 0.00%, NO_CRC: 0.00% # RF packets forwarded: 0 (0 bytes) # PUSH_DATA datagrams sent: 0 (0 bytes) # PUSH_DATA acknowledged: 0.00% ### [DOWNSTREAM] ### # PULL_DATA sent: 2 (0.00% acknowledged) # PULL_RESP(onse) datagrams received: 0 (0 bytes) # RF packets sent to concentrator: 0 (0 bytes) # TX errors: 0 ##### END ##### WAlgw_receive:1428: FIFO content: Pkts: 1 fe 2 Stat: 7 Size: 6d lgw_receive:1443: [5 17] Note: LoRa packet RNING: [down] ignoring invalid packet ##### 2015-11-20 19:49:44 GMT ##### ### [UPSTREAM] ### # RF packets received by concentrator: 1 # CRC_OK: 0.00%, CRC_FAIL: 100.00%, NO_CRC: 0.00% # RF packets forwarded: 0 (0 bytes) # PUSH_DATA datagrams sent: 0 (0 bytes) # PUSH_DATA acknowledged: 0.00% ### [DOWNSTREAM] ### # PULL_DATA sent: 1 (0.00% acknowledged) # PULL_RESP(onse) datagrams received: 0 (0 bytes) # RF packets sent to concentrator: 0 (0 bytes) # TX errors: 0 ##### END ##### WARNING: [down] ignoring invalid packet WARNING: [down] ignoring invalid packet ``` Anyone have any idea what it could be? I am not sure what to set for network and passphrase in lora-network-server.conf for example, does it matter? Or is it simply not possible to send and receive with a gateway, and should I wait for my mDot? Does someone perhaps have an example global\_conf.json for EU? ---

> [@lars\_xithing](#): > > I see “Note: LoRa packet” in the packet forwarder log That’s just data being received that might or might not be a valid packet.

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) > [@lars\_xithing](#): > > Or is it simply not possible to send and receive with a gateway, and should I wait for my mDot? 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" : "", "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](http://www.multitech.net/developer/software/lora/getting-started-with-lora-conduit-mlinux/) (steps 4-7) ---

Appreciate the help. I suppose I need to wait for my node to arrive then. Everything else looks good, so looking forward to it! ---

Hi there, I’m getting results appear in the Node bit of the API - [http://thethingsnetwork.org/api/v0/nodes/02011E01/](http://thethingsnetwork.org/api/v0/nodes/02011E01/) but there is no entry for my gateway (008000000000A052) in the Gateway bit of the API. Any idea what I am missing? I have an mlinux Conduit with an MTAC-LORA-868 card. Thanks, Mark ---

@mark: this sounds like the same problem I had with my DIY gateway: [Setting up your first gateway](https://www.thethingsnetwork.org/forum/t/setting-up-your-first-gateway/37/42) My gateway wasn’t sending geo-info, and because of that, it didn’t show up in the list. ---

Ah, yes using gps\_pkt\_fwd makes it appear in the Gateways , thanks 🙂 For info gps\_pkt\_fwd has different params to basic\_pkt\_fwd - it doesn’t accept -l logfile, so you need to strip that bit out of /etc/init.d/lora-network-server where it uses the start-stop daemon to launch pkt\_fwd. Follow-up question - how do I configure or display the logitude and latitude? Mine are coming out blank.

@markstanley Just looked at your write-up. Thank you for creating it, however two remarks (I do not want to start modifying your work right away): - Have you read my messages concerning the difference in (correctly) received packets between gps\_pkt\_fw and basic\_pkt\_fwd? If you want to be shown active on TTN I strongly suggest you try my build of poly\_pkt\_fwd for the MultiTech. Otherwise stay on basic\_pkt\_fwd if you want reliable packet reception and forwarding and do not need to be shown active. (poly\_pkt\_fwd is a ‘drop in’ replacement for basuc\_pkt\_fwd with regards to the command line arguments) - Not everyone with a MultiTech gateway will have mdots, as a result not everyone needs to sign-up @ mbed. Also people without an MultiTech gateway might use mdots, so may-be it would be better to split it into two pages? ---

@markstanley You need to use the example global\_conf.json included as the newer versions of the software made more settings configurable. Alternatively the GitHub repo has example data for both 868 and 915 MHz setups.
