joinOTAA not working on 1310 and US915

[Spinnaker-design]

I'm trying connect my MKRWAN 1310 to The Things Network. I have a device configured for OTAA setup in the TTN and when I run FirstConfiguration and enter the APP EUI and APP Key, I actually see the device connect in the TTN console immediately, but after about 30 seconds, joinOTAA returns 0.

I actually see additional activation calls in TTN after it returns 0.

Hi @k8rapps ,
did you try US915_HYBRID band? The MKRWAN firmware is not super up-to-date and the regional specifications have slightly changed in the meantime.
The behaviour you are experiencing could be due to the gateway responding to OTAA on a sub-band you are not listening to.

Hi @facchinm

Thanks for the quick response. I tried 915_HYBRID but I am seeing the same behavior. Since the MKRWAN want firmware isn't up to date, Is there a different library I should be using?

Or do you mean the firmware on the modem?

[facchinm]

Unfortunately it's about the modem firmware 😒
I collected some ideas here #64 on how to proceed, but no time has been spent yet in the task

[Spinnaker-design]

Gotcha, guess I'll use a different board in the meantime.

If it helps, my gateway is an RAK2245 Version B

Wondering if I am having the same problem. I have an Dragino LPS8 Gateway and MKR WAN 1310 both set to US915. I am just using the 'FirstConfiguration' sample to simply test connectivity which is failing. Dragino support came back with the following; "Please make sure the MKR use the same subband as LPS8 . The US915 band has 8 sub band and the LPS8 use subband 2 as default.".

Bought a LoraSensorTile and it works fine. Anyone want an MKR WAN 1310 (pretty much a brick without proper firmware support).

I'm unfortunately experiencing the same problem. The joinOTAA returns false, but even after that, I can see the device trying to join in the TTN gateway traffic inspector =(

I have had the same problem. I am using MKR WAN 1310 and have the TTN indoor gateway (in the same room). joinOTAA works for me intermittently. The problem seems to be that even though the join is accepted (as I can see from the TTN gateway console), the modem does not appear to receive the acknowledgment. I wonder if it is related to this issue (for a different hardware):

In any case, adding a delay(5000) between modem.begin(US915) and modem.joinOTAA(..) makes joining much more reliable. I am not sure why.

I'm having the same issues as you, Marek. -- Intermittent connection success to a TTN indoor gateway from across my house using otaa. I do see messages from the device in the TTN console as it attempts to connect but often modem.joinOTAA fails.

Any updates to this bug? I'm using MKRWAN.h version 1.0.13. My MKRWAN 1310 returns:

"Your module version is: ARD-078 1.2.0"

Anyone have better luck with ABP activation?

[facchinm]

Hi @digamesystems ,
the gateway is very likely "rejecting" some of the bands being configured by US915.
You can try setting US915_HYBRID which restricts the channels.
We are actively working on a solution to land on fw 1.3.0 (with all the new regional specifications fixed)

I also have the MKRWAN 1310 using RAK7258 and TTN. My problem is that there is never a join that I can see on TTN in the GW traffic. I have tried FirstConfiguration and LoraSendAndRecieve (modified for my HW) and both never get past this line in the code:
int connected = modem.joinOTAA(appEui, appKey);
It just hangs somewhere in there and never returns to my sketch.
I have also tried US915_HYBRID.
It would be a good idea if that join code would provide feedback instead of just hanging forever.
Any date for fw 1.3.0? Any idea if this problem would be fixed?
Thanks.

I am having the same issue, any updates on this?

[hpssjellis]

I am having the same issue with the US915 but with the new Lora Vision Shield. Any updates would be appreciated. I will try the delay(5000); after the begin(US915)

I am using RAK7258 and a MKRWAN 1310. After trying everything this is what I did to make it work.

1. I updated the MKRWAN library to version 1.0.15
2. Updated the MKRWAN FW using the MKRWANFWUpdate_standalone sketch
3. Use the following in your sketch:

   modem.begin(US915_HYBRID);
   modem.joinOTAA(appEui, appKey);
   modem.setPort(10);
   modem.dataRate(3);
   modem.setADR(true);

4. Update the RAK7258 to the latest FW
5. RAK7258 - Change frequency plan to sub-band channel 0~channel 7, channel 64

After this, my arduino connects every time without issues.
