Hi Ekwus, I have been running your Alora code for a while now, and it have been working OK. Lately I have several crashes, and I cant fix it. Do you know whats causing this ?

ekwus commented 5 years ago

Hey

I've not check the Alora library in a while, maybe The Things Network API has changed. I'll try and find some time later to get the test system running to check that.

If you can provide a stack trace from your error that might help pin point this specific issue.

Cheers

Dave

This is what I could get out

hjojohan commented 5 years ago

This is another screenshoot. Hope it can be of some help, tracking down this nasty bug :-)

ekwus commented 5 years ago

Hey

The payload_raw property of the data being received from TTN looks to be null! Either the API has changed or the service/message configuration has been changed on the TTN side

hjojohan commented 5 years ago

So could you please do a workaround then if your code detects that the rawmessage is null then do nothing to avoid crash, The message dont contain anythin of value anyway.. That the rawmessage isnull maybe is caused by faulty device or gateay ?

ekwus commented 5 years ago

I've made a few changes to check for null and catch any exception thrown when the messages are being deserialised.

You should be able to pull the latest nuget package and give it a live test.

I downloaded and installed the new packet and running again, lets see if we can running without unwanted stopps related to bad devices. -Thanks alot Ekwus :-)
