Now I recognized it's also when Ack is not required... But I got stacktrace:

This one solved by fix downlink messages

but still downlink messages are not catched by host. Maybe some other problem with tester, have to check more... Atleast it does not longer panic

Hi,

anything new to this? I have got the same problem.

Thanks a lot.

VladoPortos commented 5 years ago

Same issue here, might this be cause be firewall ? I mean the lora GW backend is on the wifi but the wifi router would not forward connection toLoraGW from outside ( from app server / lora server ) ... also how to handle 2 LorGW on one NW when firewall can forward port 1700 only to one specific IP ?

VladoPortos commented 5 years ago

Nope its not firewall, I have enabled NAT to specific LoraGW on the network, had only one turned on... Send message, message is sent ok, it appears in LoraApp server ... LoraGW crash with error ( same as in this topic ) and no ACK is received. No idea what might be the issue.

VladoPortos commented 5 years ago

Solved the crashes using one of the pull request builds, but the ACK still never arrive to sender, I have no idea now where the issue can be... I'll wait for proper LoraGW and see if its in this 1Ch build or somewhere else in the pipes

petrkr commented 5 years ago

You can use RTL-SDR to measure if it transmits. For me it transmits, but node does not "hear" it. Now I have Rpi based fullGW and it works. So I wonder where is problem... Anyway that guru meditation error when downlink is permormed was solved by change "to" to "as" at JSON object.. Check my comment.

VladoPortos commented 5 years ago

I'm waiting for custom PCB to connect my RAK831 to rPi and test it out... also ordered some build ( one box ) LoraAPs

kami83 commented 5 years ago

Hi,

i changed "to" to "as" and after this i get on TTN always the message that everything runs fine?
