Re: Anyone familiar with the Waveshare GSM/Bluetooth Hat?

Wed Jul 31, 2019 9:06 am


I purchased the GSM/GPRS/GPS hat for my PI3B+ and a low cost SIM from french local provider. I had some difficulties to establish a serial communication. The working configuration is (from my laptop at this stage)
- set the jumper to A (USB <=> serial)
- check usb connection using dmesg | grep USB
- chmod 777 /dev/ttyUSB0 (i don't know if it realy requiered but now it works)
- putty serial /dev/ttyUSB0
I don't know why minicom seem not working but for my tests on PI, I would need it (I connect to my PI throu ssh) and putty requires a X server.

Now I have a big issue : few seconds after entering my pin using AT +CPIN=<my pin here> hat shuts down (yet hat telling me that call and sms are ready) .

Does anybody encountered the same issue?

Thank you for this interesting link.
Actually, it seems the USB <=> UART connection delivers not enough power during GSM startup phase (just after entering the PIN code) and very often, it simply shuts the hat down. Hopefully UART works perfectly. Nota: don't forget to enable serial communication and disable the "serial login" in the rasp-config.

Sim 868 connexion à internet
Matériel utilisé :
-carte Raspberry pi 3B+ - module SIM868

Procédure à suivre :
Le module doit être branché suivant la procédure. 1- Mettre à jour le système : sudo apt-get update && sudo apt-get upgrade puis sudo reboot. 2- Sudo nano /boot/config.txt tout en bas écrire : « enable_uart=1 »

3- Sudo apt-get install ppp

4- Sudo -i cd /etc/ppp/peers/ wget https://raw.githubusercontent.com/adafr ... aster/fona - nano fona écrire « orange » après le « -T» à la place des « **** » et « /dev/serial0 » en dessous de « 115200 »

5- Sortir de sudo -i : puis taper Sudo raspi-config une fenêtre s’ouvrira, sélectionné : -interfacing option puis -serial puis -non puis -oui puis -ok sauvegarder et redémarrer, brancher le modem pendant le redémarrage.

6- Sudo ifconfig eth0 down Sudo ifconfig wlan0 down

7- Allumer le modem

8- Sudo pon fona

9- Tester le ping : ping google.com

10- Ifconfig (vérification de pp0) https://www.digikey.com/en/maker/projec ... c5c1dc2ff0

fonctionne avec une carte sim de chez orange

I am busy with a project using a Raspberry PI and have successfully done a proof of concept where I monitor input from the GPIO pins and send the info to a website using a https post request from where I send SMS's, monitor response etc etc
..... Basically, PI 3B python3/sqlite3/request and I2C for the 16X2 LCD display. Working very well using a wifi connection

So .... My challenge

I am trying to get this working on the PI zero 1.3 with raspian lite (uname -a 4.14.34+)

All the python related stuff is up and running

Installed a Waveshare GSM/GPRS/GNSS hat piggy backed onto the GPIO pins of the PI for the internet connection (Future GPS and Bluetooth as well)

Working SIM is installed in the hat and I have the 2 jumpers in the B position (PI-SIM868) (I have the net LED flashing every 3 seconds)

Installed minicom and can connect to /dev/ttyAMA0 and it responds to ATcommands ...

I have 3 basic issues to resolve and hope for any guidance from this forum

1. How do I configure and activate the GPRS connection for internet access?

2. How do I access other GPIO pins for my other inputs/outputs with the HAT in place?

3. How do I power up the hat automatically when the PI powers up?

I am based in Johannesburg (South Africa)


Hi Arnold,

Did you ever get this to work ? I’m having issues to connect to my device. Any help will be much appreciated.

Also a fellow South African... now living in Texas.

Please help. I’m about to give up with this HAT.
