Hi, i have swarm m138 that i used with gui in windows 11.
I tried receive test command and get “RSSI=-102*1e”. Other than that, i dont see any extra messages containing SNR and FDEV eventhough there is sattelite passes from my location.
Does anyone have any ideas as to what is causing the problem or what to try to fix it?
Hello @ozaanme,
The current list of approved countries / regions for the M138 Modem is: USA, Antarctica, Australia, Austria, Brazil, Canada, Colombia, Denmark, Georgia, Germany, Greenland, Iceland, Ireland, New Zealand, Netherlands, Spain, Sweden, United Kingdom and International Waters (12 nautical miles offshore). Turkey is not currently included. But I would still expect you to be able to detect the satellites. Where is your antenna located? Does it have a clear view of the sky? Are you using the ground plane?
Best wishes,
Paul
The antenna has a clear view of sky and I use it with the ground plane. As far as I understand, when I run the receive test, regardless of my location, I should be able to get SNR and FDEV values.
Very strange… -102 RSSI is good…
There are still some gaps in the Swarm coverage hour-by-hour. Please check the Pass Checker:

Also, please try raising your antenna above ground level. Other customers have posted useful information on the product page:
“As some of the reviewers pointed out the location of the sensor node (antenna) is critical. I also found that very low (RSSI -106) is not necessarily a trouble-free communication. Sometimes I was able to get them working with high RSSI -92 but not able to communicate with -106 RSSI. My advice to users of SWARM is not to get discouraged if you have initial setting up problems due to poor antenna locations.”
“One IMPORTANT note - my testing has shown that the antenna MUST be at least a couple of meters above everything around it. My initial install a meter above the low corner of my roof led to VERY poor performance. Thankfully I didn’t just toss the device… moving the antenna a few meters above other obstructions made all the difference in the world. Don’t repeat my initial mistake!”
I hope this helps,
Paul
