Hi, I didn't found information in Telit documentation about the GPS control with QMI. I'll try to poke them directly. On the other side, I did enable the gps with success using mmcli but didn't had any data location under the --location-get command. Here is the log when I do the command mmcli -m 0 --location-enable-gps-nmea if you ever see something unusual. ---------------------------------------------------------------------------------- <debug> [1587919447.966940] Got QMI WDS event report <debug> [1587919448.098691] Setting up location sources: '3gpp-lac-ci, gps-nmea' <debug> [1587919448.098791] Location '3gpp-lac-ci' gathering is already enabled... <debug> [1587919448.098826] Location 'gps-raw' gathering is already disabled... <debug> [1587919448.098855] Location 'agps-msa' gathering is already disabled... <debug> [1587919448.098880] Location 'agps-msb' gathering is already disabled... <debug> [1587919448.098901] Need to enable the following location sources: 'gps-nmea' [/dev/cdc-wdm0] sent message... <<<<<< RAW: <<<<<< length = 38 <<<<<< data = 01:25:00:00:10:03:00:03:00:22:00:19:00:13:04:00:E8:03:00:00:12:04:00:02:00:00:00:10:04:00:01:00:00:00:01:01:00:10 [/dev/cdc-wdm0] sent generic request (translated)... <<<<<< QMUX: <<<<<< length = 37 <<<<<< flags = 0x00 <<<<<< service = "loc" <<<<<< client = 3 <<<<<< QMI: <<<<<< flags = "none" <<<<<< transaction = 3 <<<<<< tlv_length = 25 <<<<<< message = "Start" (0x0022) <<<<<< TLV: <<<<<< type = "Minimum Interval between Position Reports" (0x13) <<<<<< length = 4 <<<<<< value = E8:03:00:00 <<<<<< translated = 1000 <<<<<< TLV: <<<<<< type = "Intermediate Report State" (0x12) <<<<<< length = 4 <<<<<< value = 02:00:00:00 <<<<<< translated = disable <<<<<< TLV: <<<<<< type = "Fix Recurrence Type" (0x10) <<<<<< length = 4 <<<<<< value = 01:00:00:00 <<<<<< translated = periodic-fixes <<<<<< TLV: <<<<<< type = "Session ID" (0x01) <<<<<< length = 1 <<<<<< value = 10 <<<<<< translated = 16 [/dev/cdc-wdm0] received message... <<<<<< RAW: <<<<<< length = 20 <<<<<< data = 01:13:00:80:10:03:02:03:00:22:00:07:00:02:04:00:00:00:00:00 [/dev/cdc-wdm0] received generic response (translated)... <<<<<< QMUX: <<<<<< length = 19 <<<<<< flags = 0x80 <<<<<< service = "loc" <<<<<< client = 3 <<<<<< QMI: <<<<<< flags = "response" <<<<<< transaction = 3 <<<<<< tlv_length = 7 <<<<<< message = "Start" (0x0022) <<<<<< TLV: <<<<<< type = "Result" (0x02) <<<<<< length = 4 <<<<<< value = 00:00:00:00 <<<<<< translated = SUCCESS [/dev/cdc-wdm0] sent message... <<<<<< RAW: <<<<<< length = 24 <<<<<< data = 01:17:00:00:10:03:00:04:00:21:00:0B:00:01:08:00:04:00:00:00:00:00:00:00 [/dev/cdc-wdm0] sent generic request (translated)... <<<<<< QMUX: <<<<<< length = 23 <<<<<< flags = 0x00 <<<<<< service = "loc" <<<<<< client = 3 <<<<<< QMI: <<<<<< flags = "none" <<<<<< transaction = 4 <<<<<< tlv_length = 11 <<<<<< message = "Register Events" (0x0021) <<<<<< TLV: <<<<<< type = "Event Registration Mask" (0x01) <<<<<< length = 8 <<<<<< value = 04:00:00:00:00:00:00:00 <<<<<< translated = nmea [/dev/cdc-wdm0] received message... <<<<<< RAW: <<<<<< length = 20 <<<<<< data = 01:13:00:80:10:03:02:04:00:21:00:07:00:02:04:00:00:00:00:00 [/dev/cdc-wdm0] received generic response (translated)... <<<<<< QMUX: <<<<<< length = 19 <<<<<< flags = 0x80 <<<<<< service = "loc" <<<<<< client = 3 <<<<<< QMI: <<<<<< flags = "response" <<<<<< transaction = 4 <<<<<< tlv_length = 7 <<<<<< message = "Register Events" (0x0021) <<<<<< TLV: <<<<<< type = "Result" (0x02) <<<<<< length = 4 <<<<<< value = 00:00:00:00 <<<<<< translated = SUCCESS ----------------------------------------------------------------------------------
By curiosity, do you know a good references for qmi protocol so I can dig into it?
