No Support for GPS/GNSS data ?

[salmanfarisvp]

Is there any example sketch to access the GPS/GNSS data?

https://github.com/Seeed-Studio/Wio_LTE_Arduino_Library this one supported GNSS but it doesn't have the Soracomm example.

Hi @salmanfarisvp We are not providing GNSS support on this library because somehow the cellular module used on Wio LTE JP version doesn't have that function. So actually this is the first time to hear the GNSS support request. Which version of Wio LTE are you trying to use in where?

Hi @ytsuboi As a part of the Hackster Soracom contest (https://www.hackster.io/contests/soracomcontest), I received the WIO LTE v1.3b Europe Kit, and for my application, I need both GSM and GNSS, but the lib provided with the doc can't find any information about GPS, but my module is capable of GPS. Is there any way to get the GPS coordinate data

version : WIO LTE v1.3b Europe Location : Kerala, INDIA

@salmanfarisvp, I did a try and got the GNSS example from Seeed-Studio/Wio_LTE_Arduino_Library working on the EU board.

I will try to port the GNSS functionality to this library. I will let you know when is done.

The GNSS functionality is implemented in this class: https://github.com/Seeed-Studio/Wio_LTE_Arduino_Library/blob/master/gnss.cpp

@ytsuboi, when done I think we can integrate the GNSS library here. So, at least non-JP users would be able to use it. It's strange why Quectel choose to not support GNSS for the EC21-J.

Thanks, Attila

@bluetiger9 Thank you, I will also trying to implement .

Added basic GNSS functionality to the library. Getting coordinates (lat + long), altitude and UTC time are supported.

For anyone interested, the changes are located in the bluetiger9/WioLTEforArduino repository. They can be merged (copied) into the <HOME>/Arduino/libraries/Wio_LTE_for_Arduino folder.

Also added an example: Wio LTE for Arduino -> gnss -> GetGNSSLocation. This should be visible after the Arduino IDE is restarted.

Thank @bluetiger9 it's working.

@bluetiger9 , now it showing some error, can you please take a look .

## I/O Initialize.
### Power supply ON.
### Power supply GNSS.
### Turn on or reset.
### Enable GNSS.
### ERROR! ###
### Get GNSS location.
### ERROR! ###
### Get GNSS location.

I used the example GNSS skecth

@bluetiger9 @ytsuboi Please take a look https://github.com/SeeedJP/WioLTEforArduino/pull/27

Can you enable WIO_DEBUG macro and get log at SeeedJP:master branch ?

https://github.com/SeeedJP/WioLTEforArduino/blob/master/src/WioLTEConfig.h#L17

Hi @matsujirushi,

I can confirm that the GNSS does not always works without the retry mechanism.

@salmanfarisvp

Can you enable WIO_DEBUG macro and get log at SeeedJP:master branch ?

https://github.com/SeeedJP/WioLTEforArduino/blob/master/src/WioLTEConfig.h#L17

Here are the debug logs:

• without retry:

  ### Enable GNSS.
  <- AT+QGPS=1
  -> 
  -> ERROR
  -> 
  -> +CFUN: 1
  -> 
  -> +QIND: SMS DONE
  -> 
  -> +QIND: PB DONE
  ### TIMEOUT ###
  ERROR! 1207
  ### ERROR! ###

• with retry:

  ### Enable GNSS.
  <- AT+QGPS?
  -> 
  -> +QGPS: 0
  -> 
  -> OK
  -> 
  -> +CFUN: 1
  -> 
  -> +QIND: SMS DONE
  -> 
  -> +QIND: PB DONE
  ### TIMEOUT ###
  <- AT+QGPS=1
  -> 
  -> OK
  <- AT+QGPS?
  -> 
  -> +QGPSURC: "xtradataexpire",0,"1980/01/05,19:00:00"
  -> 
  -> +QGPS: 1

Hi all, I modified EnableGNSS().

@bluetiger9 @salmanfarisvp Please test SeeedJP:dev-gnss code. Thanks.
