1020 +=== 6.5.1 GPS commands ===
1021 +
1022 +
1023 +The following are three related AT commands that introduce GPS functions.
1024 +
1025 +* **Turn on/off GPS**
1026 +
1027 +(% style="color:blue" %)**AT Command: **(% style="color:#037691" %)**AT+GPS **
1028 +
1029 +**Ex1:  **AT+GPS=0  ~/~/ Turn off GPS
1030 +
1031 +**Ex2:  **AT+GPS=1  ~/~/ Turn on GPS
1032 +
1033 +(% style="color:blue" %)**Downlink command:**(%%)** (% style="color:#037691" %)0x11(%%)**
1034 +
1035 +Format: Command Code (0x11) followed by 1 byte.
1036 +
1037 +Example:  Downlink Payload: **11 01   **~/~/ AT+GPS=1
1038 +
1039 +* **Set GNSS open time**
1040 +
1041 +Extend the time to turn on GNSS. The automatic GPS location time is extended when the node is activated.
1042 +
1043 +(% style="color:blue" %)**AT Command: **(% style="color:#037691" %)**AT+GNSST**
1044 +
1045 +Example: AT+GNSST=30  ~/~/ Set the GPS positioning time to 30 seconds
1046 +
1047 +(% style="color:blue" %)**Downlink command:**(%%)** (% style="color:#037691" %)0x10(%%)**
1048 +
1049 +Format: Command Code (0x10) followed by 2 bytes.
1050 +
1051 +Example:  Downlink Payload: **10 00 1E    **~/~/ AT+GNSST=30
1052 +
1053 +* **Set GPS positioning interval**
1054 +
1055 +Feature: Set GPS positioning interval (unit: hour).
1056 +
1057 +When GPS is enabled, the node automatically locates and uplinks each time it passes **GTDC time** after activation.
1058 +
1059 +(% style="color:blue" %)**AT Command: **(% style="color:#037691" %)**AT+GTDC**
1060 +
1061 +Example: AT+GTDC=24  ~/~/ Set the GPS positioning interval to 24h.
1062 +
1063 +(% style="color:blue" %)**Downlink command:**(%%)** (% style="color:#037691" %)0x12(%%)**
1064 +
1065 +Format: Command Code (0x12) followed by 3 bytes.
1066 +
1067 +Example: 24 hours:  24(D)=0x18(H)
1068 +
1069 +Downlink Payload: **12 00 00 18   **~/~/ AT+GTDC=24
1070 +
1071 +
1072 +=== 6.5.2 GPS workflow ===
1073 +
1074 +
1075 +The whole working process after the GPS function is enabled((% style="color:#037691" %)**AT+GPS=1**(%%)) is as follows:
1076 +
1077 +~1. When activate the node, the node will turn on the GNSS, if the GPS signal is good, the node will print and upload the position information with the first data packet immediately.
1078 +
1079 + If the signal is not good, it may take the whole (% style="color:#037691" %)**GNSST**(%%) time but still can not search the latitude and longitude information, at this time the node uploads the latitude and longitude all to 0.
1080 +
1081 + So if there is a failure of positioning, the user can extend the (% style="color:#037691" %)**GNSST**(%%) time appropriately.
1082 +
1083 +2. Each TDC time node is not repositioned and the positioning interval is determined by the AT+GTDC time.
1084 +
1085 + The latitude and longitude payload uplinked at each TDC time is the GPS positioning information from the previous (% style="color:#037691" %)**GTDC**(%%) time.
1086 +
1087 + Only when the node is activated or every (% style="color:#037691" %)**GTDC**(%%) time is reached, the node turns on the GNSS and we can observe the GPS search information through the serial assistant or Bluetooth tool.
1088 +
1089 +
1090 +=== 6.5.3 GPS debugging methods ===
1091 +
1092 +
1093 +In summary, we can deduce the methods of debugging GPS:
1094 +
1095 +* **Check whether the GPS function is enabled.**
1096 +
1097 +[[image:image-20240903102327-5.png||height="271" width="529"]]
1098 +
1099 +* **Check whether the GPS antenna is loose**.
1100 +
1101 +If the GPS antenna is loose, the GPS signal is weak, and the positioning fails.
1102 +
1103 +[[image:image-20240903094214-1.png||height="340" width="461"]]
1104 +
1105 +* **Use the AT+GNSST command to extend the positioning time.**
1106 +
1107 +The default AT+GNSST=30, that is, the default positioning time is 30 seconds.
1108 +
1109 +If the location fails, users can extend the location time.
1110 +
1111 +[[image:image-20240903102641-8.png||height="303" width="600"]]
