ST-901 Engine cutoff
Are the devices' firmware upgradable through the SinoTrack servers ?
You mean Over The Air (OTA) firmware update via platform server? That I am still discovering. I know they use USBASP header port update to their micro controller.
I'm familiar with the commands you've listed. Have send then either via SMS or through the Traccar custom command.
It's only the CXZT command that's evading me. I get no reply if I sms it or via the Traccar custom command and have never used any of the SinoTrack servers.
