>
11345+
> **quecgnss.init()**
11346+
11347+
* Function
11348+
11349+
Initialization of GNSS module functions.
11350+
11351+
* Parameter
11352+
11353+
None
11354+
11355+
* Return Value
11356+
11357+
Returns integer 0 on success, integer -1 on failure.

11363+
> **quecgnss.get_state()**
11364+
11365+
* Function
11366+
11367+
Get the GNSS module status.

11369+
* Parameter
11370+
11371+

11374+
11375+
| Value | Type | Description |
11376+
| ----- | ---- | ------------------------------------------------------------ |
11377+
| 0 | int | The GNSS module is closed |
11378+
| 1 | int | The GNSS module is being firmware upgrade |
11379+
| 2 | int | The GNSS module is positioning. In this mode, the GNSS module starts to read GNSS positioning data. The validity of the positioning data needs to be determined by parsing corresponding statements after obtaining the positioning data, for example, whether the STATUS of the GNRMC statement is A or V. A indicates that the positioning is valid, and V indicates that the positioning is invalid. |

##### Enable or disable GNSS
11384+
11385+
> **quecgnss.gnssEnable(opt)**
11386+
11387+
* Function
11388+
11389+
Enable or disable the GNSS module. If you use the GNSS function for the first time after power-on, you do not need to invoke this interface to enable the GNSS function. Instead, you can invoke the init() interface. The init() interface automatically enables the GNSS function during initialization.
11390+
11391+
* Parameter
11392+
11393+
| Parameter | Type | Description |
11394+
| --------- | ---- | ------------------------------------ |
11395+
| opt | int | 0 - disable GNSS<br/>1 - enable GNSS |
11396+
11397+
* Return Value

11416+
11417+
* Return Value
11418+
11419+

Module function: the module provides a bare flash area and a special read-write interface for customers to store important information, and the information will not be lost after burning the firmware (burning the firmware without this function cannot be guaranteed not to be lost). Provide a storage and read interface, not a delete interface.
