Hi
We are using miniPCIe Huawei ME909u-521, and trying to use GPS positioning
We tested RouterOS 6.27 y 6.26 (the only ones that support ME909u-521) with routerboard RB953GS5HNT
We tested with three different GPS antennas (passive because it is what the ME909u requires) and most of the times we don’t get position from the GPS module, we can’t find any cause for it, and getting position from GPS is completely random.
We tried different GPS module configuration with AT commands including the recommended ones by Huawei
AT^WPDOM=0
AT^WPDST=1
AT^WPDFR=65535,1
AT^WPQOS=255,500
AT^WPDGP
Usually we get the below NMEA results, that indicate we see enough satellites but all of them have SNR missing (I have read that this is because they are not being used, but we see azimuth and elevation), the below one is seeing 10 satellites
$GLGSV,3,1,10,70,29,091,86,51,307,77,13,333,76,49,284,*6F
$GLGSV,3,2,10,75,33,205,69,16,033,84,04,067,87,08,267,*65
$GLGSV,3,3,10,85,45,037,71,11,140,*6F
Anyone has GPS working with this Huawei card?
Thanks in advance
