I have an ST P-Nucleo-LRWAN2 kit: P-NUCLEO-LRWAN2 - STM32 Nucleo pack LoRa™ HF band sensor and gateway - STMicroelectronics
I followed their instructions (User Manual UM2587), and it was all working on Tuesday (19th).
The Gateway uses the ‘legacy Semtech packet forwarder’.
I could see traffic in the Gateway console view, and in the Device console view:
On the I-Nucleo-LRWAN1 device, the green LED blinks each time it transmits - I could see that a new payload appeared in the Device console view corresponding to each blink.
Some time in the latter part of Wednesday (20th), I noted that the LED had stopped blinking.
On Thursday (21st), looking at the Console, I saw that the Gateway status was ‘Not Connected’, and there was no data in the Device view.
I tried restarting the Gateway (AT+RESET), but that made no difference.
I found forum posts saying that ‘Not Connected’ could simply mean that there’s no data going through the Gateway.
So I power-cycled the Device.
This did start the LED blinking again, but the Console views showed only Join requests - no actual data messages.
(screenshot uploads seem to be broken now)
The Gateway did seem to be sending Join accepts, but the device never seemed to see them - it just carried on sending requests.
Another forum post mentioned that the device message counters might be out-of-sync - so I did a ‘Reset Frame Counters’ on the Device Overview console page.
This made no difference.
A different device (WizziLab SH2050 shield, in LoRaWAN mode) was able to join & send data OK.
So I left the ST kit for a while - and it just started working again later in the day (Thursday).
This morning (Friday, 22nd), I see that the ST device has stopped blinking again!
(the WizziLab is still working).
The ST device is as-received - no configuration changes or firmware updates.
As supplied, it transmits every ~ 40s.
Is this too much? Is TTN “blacklisting” it, or something?
I’ll be posting on the ST forum, too.
I guess the main question here is, what is the best way to diagnose this stuff on TTN?
The trouble with the Console traffic views is that they seem to keep only a little history while the page is open, and that is all lost when you navigate away from the page.
Is there a way to get long-term logs?
