RomanParticipantAndrew, thank you for response!
– Is there an event that consistently leads to lost GPS lock?
– Yes, jamming.– Does your GPS antenna have access to clear sky?
– Yes, sure.– Is it possible one of the messages is configuring the device in an undesirable state?
– We haven’t got possibility to reproduce main problem with devices under jamming. But we can get simmilar behavior if we send coldboot command [ 0xB5, 0x62, 0x06, 0x04, 0x04, 0x00, 0xFF, 0xFF, 0x01, 0x00 ], 9th byte (0x01) repesents “Reset Type”
0x00 = Hardware reset (watchdog) immediately
0x01 = Controlled software reset
0x02 = Controlled software reset (GNSS only)In case of 0x02(Controlled software reset (GNSS only)) it continue work(without jamming) but it doesn’t help for devices under jamming.
Unfortunately its bad news that we can’t get GPS info without lock status.
We wanna try to connect external GPS. Will it be possible to get proper timestamp in spectrum and IQ traces from external GPS?
Also will be possible to communicate with external GPS through sm_api?- AuthorPosts
