Hi - I recently got a FMB920, which is a pretty great hardware/software overall *BUT* towing detection misfires and sends false negatives multiple times a day/night! Effectively useless for the main purpose.
After a few false positives, I maxed all params that I thought may be relevant:
FMB920,03.25.15,32,354018110591884,2020/07/13 12:56,1.7,164kB/346kB,120MB/122MB,TM25Q_R_01.00.03.00_000,2,841,AXN_5.10_3333,1,0,2,0
Param ID:11605 Value:5.000000
Param ID:11606 Value:1.000000
Param ID:11607 Value:2000
I also sent info@teltonika.com a request for a newer firmware if that exists - pending a response.
Kind regards!
