Gateway Reboots after Downlink attempt

[kulsoomjafri]

Hi,
Sincere compliments and kudos for the good work. I have been using gateway since version "V.5.3.3.H; 180825a", now upgraded at "V.6.2.3.E.EU868; PlatformIO 200223a"
The issue arose in V.5.3.3 whenever I sent a message. I realized that payLength was zero. I was running into the issue on V.5.3.3 which I fixed locally by adding the following in _loraModem.ino line 780

 if (payLength>0)
 {
	sendPkt(payLoad, payLength);
 }

The error in this version is as follows:

Stack smashing protect failure!

abort() was called at PC 0x400f3960 on core 1

Backtrace: 0x4008cc2c:0x3ffb18c0 0x4008ce5d:0x3ffb18e0 0x400f3960:0x3ffb1900 0x400d6cde:0x3ffb1920 0x400d71e5:0x3ffb1980 0x400e042a:0x3ffb19f0 0x400e2ca3:0x3ffb1f60 0x400ef4c5:0x3ffb1fb0 0x40089341:0x3ffb1fd0

That translates to :

I tried the same approach and tried fixing it as
if (LoraDown->size>0)
But I still see the reboot issue. For now reverting back to V5.3.3

Hi,

Too bad that you have troubles with the code.
At this moment I am working on release 6.2.7.
Would it be possible to try the latest version, which would enable me to repair obvious errors?

Thanks,

Maarten

Thanks a lot for your response. Yes I will be able to test the latest version. Thanks again for all your efforts to the community.

The latest version on the site is 6.2.7 and has lots of issues fixed. I advise you to download the version.

I am now looking into the downlink issue. It seems that the software expects all downlinks to happen, but not all of them are actually sent.

Thank again Maarten for reaching out to me. I have downloaded the latest version but still having the same issue of downlink messages. I also corrected some other things in the code which I think will be useful for the users who experience restarting of their gateways after every downlink message sent from the TTN. For your reference, I am attaching the screenshot. It is located in loraModem.io [image: image.png] [image: image.png]
