Yes, I noticed it can be backordered again. But indeed a dramatic price increase. That makes the lig16 not so interesting anymore šŸ¤” ---

Managed to buy the LIG16 for an old price somewhere šŸ¤— (they increased the price right after I paid for it). The unit arrived yesterday afternoon. It already had the latest firmware installed. Setting up with ttn V3 was a breeze. It just worked immediately! ( well, I call 15 minutes after unpacking immediately) There are still some settings I am not sure about, but left those on default. I will digg into that later. So far very happy with it. In the last 12 hours I had around 150 messages from devices I can receive that were forwarded. ---

The next step for me is to get Basic Station running on the LIG16. I tried Basic Station already with my LPS8 but I got timing-errors - so back to Semtech UDP. I will see how the LIG16 behaves. ---

I googled and checked the top 3 results.

Basic Station is swingende, snaarstrakke rock & blues, stevig en gevoelig, uitbundig en ingetogen. Kortom, muziek vanuit het hart. ---

But on a more serious note, I did read this but Iā€™m too noob in lorawan to understand what the differences are with alternative solutions. Even more, I have no oversight in what alternatives exist to choose from. [https://doc.sm.tc/station/](https://doc.sm.tc/station/) ---

Thx for the links. This is getting off topic, but after reading a lot more my conclusion is that basics station has two major advantages (but correct me when Im wrong or missing something): - more secure communication between gateway and the network server (the things stack) - central provisioning when managing a lot of gateways The second advantage is not interesting for me since I only have 1 gateway. Am I missing a major advantage? I looked at the LIG16 documentation, and it should support configuring Basics Station from the web GUI. See wiki here: [Notes for TTN - Wiki for Dragino Project](https://wiki.dragino.com/index.php?title=Notes_for_TTN#Gateway_Registration_for_Basics_Station) But this option is not available in the latest stable firmware. I am considering installing the latest beta to see if it is available there. Edit: looking at the docs and the firmware levels the latest beta firmware should indeed be the right one. Will try tomorrow. ---

These are indeed two of the key, if not _the_ two key benefits. There are others, including the move away from UDP based comms - not only more secure but also more resilient than UDP, as used for the original Semtech (oft Aka ā€˜Legacyā€™) Packet Forwarder as UDP packets often go astray or get dropped as they transit ā€˜the netā€™. - So secure comms not only in the sense of being authenticated and hence from a known reliable source vs rogue/unauthorised hijacking GW but also secure in terms of greater probablility of packet delivery. ---

Will try tomorrow. Iā€™d respectfully suggest you do an install with what you have so you have a good chance of having a working gateway and learn the basics of devices, the console, integrations etc etc before going for the juggling of fire brands on a unicycle. ---

This morning I tried to connect my LIG16 to TTS Basic Station using the beta firmware. I could connect without problems, data-packages were transferred from my gateway to TTS. I could see all my nodes in their applications. But then I observed that the system-log of my gateway filled up with ā€œTime sync rejectedā€-messages. ```auto 2021-09-11 06:58:14.551 [SYN:INFO] Mean MCU drift vs SX130X#0: -1.8ppm 2021-09-11 06:58:33.457 [SYN:VERB] Time sync rejected: quality=346 threshold=340 2021-09-11 06:58:46.060 [SYN:VERB] Time sync rejected: quality=341 threshold=340 2021-09-11 06:58:56.563 [SYN:VERB] Time sync rejected: quality=346 threshold=340 2021-09-11 06:59:02.865 [SYN:VERB] Time sync rejected: quality=379 threshold=340 2021-09-11 06:59:04.965 [SYN:INFO] MCU/SX130X drift stats: min: +0.0ppm q50: +3.6ppm q80: +7.4ppm max: -12.4ppm - threshold q90: +8.6ppm 2021-09-11 06:59:04.965 [SYN:INFO] Mean MCU drift vs SX130X#0: -1.3ppm 2021-09-11 06:59:11.267 [SYN:INFO] Time sync qualities: min=272 q90=346 max=379 (previous q90=340) 2021-09-11 06:59:24.921 [SYN:ERRO] Repeated excessive clock drifts between MCU/SX130X#0 (3 retries): 11.4ppm (threshold 8.6ppm) 2021-09-11 06:59:28.072 [SYN:ERRO] Repeated excessive clock drifts between MCU/SX130X#0 (6 retries): 8.8ppm (threshold 8.6ppm) 2021-09-11 06:59:35.425 [SYN:VERB] Time sync rejected: quality=376 threshold=346 2021-09-11 06:59:41.726 [SYN:INFO] MCU/SX130X drift stats: min: +3.3ppm q50: +8.3ppm q80: +11.0ppm max: +17.6ppm - threshold q90: +13.3ppm 2021-09-11 06:59:41.726 [SYN:INFO] Mean MCU drift vs SX130X#0: 7.0ppm ``` Additionally nothing was shown anymore in LogRead/ Gateway Traffic of the LIG16.

Hi @wolfp have you refered this back to Dragino team - would be interested to get their take on thisā€¦ Please report back here if you hear anything. Also is there an option to reduce the amount of logging within the setup? This feels like debugging level logs. ---

I tried just as you this morning. Connection works well. I also get time sync rejected errors after some time. But I think it is also able to correctly do time sync.

> [@wolfp](#): > > Additionally nothing was shown anymore in LogRead/ Gateway Traffic of the LIG16 That is just a GUI thing of the webinterface. When I refresh the page I get to see new logs. Edit: gateway traffic graph stays empty indeed. But in theThingsStack I see normal traffic coming in. I have tested Basics Station for about an hour now, and I seem to get all uplink messages and am also able to do downlink messages. I will keep the LIG16 configured as it is for now and see how it behaves on the long term. ---

I am testing a LIG16. I flashed the newest firmware OpenWRT 18.06, Version: Dragino-v2 lgw-5.4.1636008262, Build Thu Nov 4 14:44:22 CST 2021 I can join TTS-CE for both modes: UDP forwarder 1700 and basic station 443. Now, i want to join a private TTS server but i canā€™t do it theā€¦ easy way. This server has some Lorix one GWā€™s running fine and they join by basic station port 8887. So, any use cases for LIG16 and private TTS servers ? ---

So, no one tried connecting to a LNS basic station port 8887 on a dragino LIG16 ? ---

There is a new firmware available from Dragino for LIG16. This one allows the user to provide his own server certificate so itā€™s usable for any TTS scenario.
