I'm using Stretch installed Raspberry Pi 3 B and Waveshare GSM/GPRS/GNSS HAT to obtain GPS real-time location and internet.

What I have done :

  • Used USB-UART interface and connected jumper
  • Using Python 3 & obtained location details successfully
  • For internet - followed https://www.waveshare.com/wiki/SIM868_PPP_Dail-up_Networking this and able to connect internet (ttyUSB0 was used)> But the connection is very slow (always ping succeeded) I was not able to activate the 3G connection though I update with APN of the service provider.

What I expect :

  • A method of obtaining GPS location while having internet at the same time from this module.
  • To activate the 3G connection using this module.

Any suggestion, please...

Question

Rpi3V Stretch and Waveshare GSM/GPRS/GNSS HAT for GPS an Internet.

Used USB-UART and Python 3 location OK

SIM868_PPP_Dail-up_Networking ttyUSB0 connection very slow

Not able to do 3G connection though I update with APN of the service provider.

Answer

Well, the user guide already explained why Rpi is slow. They fiddled something but using 115k baud AT command to do PPPoE is of course slow. The service provider might also set lower priority to poor 2G customers

Your board is only 2G GSM/GPRS. So you can not do 3G. Bad luck! :(

One suggestion is to use something like Hologram Nova USB Modem. See references below for more details.

Raspberry Pi GSM Module – Mobile Internet (LTE, 3G, UMTS)

The Raspberry Pi can be connected to the Internet very quickly and easily via the local network. But what if you also need a mobile Internet connection outside your own WLAN? There are GSM modules / Surfsticks (mostly from Huawei), which can be connected via USB. Sometimes are such GSM modules, which support 3G, UMTS and sometimes even LTE, given free with a mobile phone contract which includes an Internet option.

This tutorial shows how to connect Raspberry Pi to the internet using GSM modules.

  • Oh, I understood that. I was wondering why was that. Thank you very much for the explanation. Is there any option to obtain the internet from such a module except using wifi? I mean to run RPI with the internet as a separate device. I searched for different modules and bought this one but now as explained it is not working with the speed I want :( Any suggestion about an alternative option, please? Thanks again! – Sachz May 14 at 16:49
  • @Sachz Have you ever considered Hologram Nova USB Modem hologram.io/docs/reference/nova/datasheet which can do 2G to 4G? – tlfong01 May 17 at 2:32
  • Nope I haven't. I will go through it. Thank you for the suggestion with the references ! – Sachz May 22 at 5:59
  • You are welcome. Good luck! – tlfong01 May 22 at 6:08
