[dbellomo (daniel)]

Hello.
My Polysense sensor send ONLY “accept join-request” and “forward uplink data message”.
I see both messages on “application” TTN (live data).
Does not send any more data.

Please, could you help me?
Thanks!

Hello,
I think I have the same problem with GPS device (LGT-92).

Here is the screenshoot:

Hey! I also have the same problem. Did you figure it out?

[Johan_Scheepers]

How far are you from the gateway?

Wat is the RSSI?

[lakeormstruplora]

Hi all,

I also have the similar problem. Sometimes even my device could not join a gateway (personal gateway) and I am testing the device just next to gateway. Sometimes it is sending message, sometimes only join accept message, and sometimes even join is unsuccessfull. I am using Seeedunio Lorawan board. When it sends a message, SNR is mostly negative too. I do not know it is about board, gateway or server? I have tested with sevaral different Seeedunio boards and th problem is the same. Do you have any suggestions?

If you searched a small little bit and maybe read the last dozen or so post, you will have the solution maybe.

Did you try this?

WIth a technology designed for Long Range! Search forum on recommended placements when developing…

Thanks! And sorry for taking your time. Actually I spent much time in the forum but may be with the wrong keywords! I will look for optimum replacements and search a bit more.

What is the RSSI as logged in the application console?

[lakeormstruplora]

RSSI of the last successful message of one of the device was -117. But I have several devices that I could not manage to get successful join message or forward uplink message for some of them.

Unsuccessful one

[lakeormstruplora]

Sorry, probably I ve missed some points but I could only see the RSSI"s of the successful ones now. When I ll access to devices tomorrow, I will connect them and update the RSSI information here. Thanks for the help and your time!

Join Errors with RN2xx3

I am having trouble joining over otaa. LoRa Module: RN2903 Gateway: Basic Station running as a docker container on a RAK2243 PiHat on a Pi4. My node and gateway are quite close at the moment (3 meters) for this stage of development. Is this too close? Before sending the otaa join request, I set the radio sf to sf7 as I’ve read that the default sf12 can cause issues. This my configuration… RN2903_cmd("mac set deveui " HWEUI "\r\n"); RN2903_cmd("mac set devaddr 00000000\r\n"); RN2903_cmd("m…

Thank you so much! This thread seems really helpful!

[lakeormstruplora]

Hi again. It seems that closeness to the gateway was the main problem! Even one device is close, I think it also effects the join of the other devices too. Now all my devices are far away from gateway and they are all working. Thank you so much!
