And the description:

Technical issues with the Forum or the Developer Zone, improvement suggestions

So why did you choose this forum rather than the ‘Programmable modems’ forum:

FX Series and GL Series

Doesn’t that sound more appropriate to your topic

catb.org/esr/faqs/smart-questions.html#forum

Anyhow…

@grochap

two have some problems about keep the signal strong

Note that the modem itself has no control whatsoever over signal strength - so there is nothing that it can do to “keep the signal strong”.

So an important part of your installation process needs to be to consider the signal conditions at the site.

it it shows signal in 41%

What shows that

(even using an external anten) and later logger displays 15%, and finally ¨unknow¨

So the question is:

“is the signal really varying that much, or is there a fault somewhere?”

Obviously, if there is no signal, the modem cannot send anything. And, If the signal is poor, the modem will have difficulty sending.

Thus it is important that your application has an effective strategy for retries & recovery.

Strange that 2 works gracefully out of box, and 2 not.

Not strange if the 2 that work are in “easy” locations, and the 2 that don’t are in “challenging” locations…

I attach 2 images about the modem and the type of setup I have.

Unfortunately attachments aren’t working at the moment:

Uploads not working!

First here: https://forum.sierrawireless.com/t/ds-3-2-install-no-packages-found-for-sl808xt/7661/11 When I view that thread on the PC from which I posted, I see the pictures OK; when I view it from a different PC, I can’t see the pictures! And now here: https://forum.sierrawireless.com/t/invalid-gps-coordinates-reported/7670/4 So it’s not just me!
