To Start working with our PiTalk 4G HAT, set-up your Raspberry Pi or RockPi by flashing their os file and boot it, for this click here.
- After setup your Pi board, attach the PiTalk 4 HAT on it and boot by providing compatible power supply.
- Now, open the command prompt and type the following command to clone the current repository in your Pi-board.
git clone https://github.com/sbcshop/Pitalk_4G_HAT_Software.git
- After, downloading this repository you will see two directory in it. One is of Example code and 2nd one is of Library file.
- Now, open the both Example and Library directory. To open these files make sure you have python installed in your Pi board.
- In examples Directory there are some example codes to use the different functionality of PiTalk HAT you have move out the example file which you want to run from the Examples directory and after that run the code by make some editing if require.

Connect HAT on Raspberry Pi,
-
Make sure you have enabled serial interface of Raspberry Pi, if not follow guide : "Serial Interface Enable RPi"
-
Once Pi is running and HAT is getting power make sure 4G module is on, for this press and hold power key for 3-4 sec. You will get confirmation by network status LED.
-
Follow setup guide provided here in github : "Steps for 4G HAT Internet on Raspberry Pi"
-
We have also provided the USB feature in our PiTalk 4G HAT to use this HAT as dongle. For this you have to to install its USB driver provided in this Repository. For this download and unzip the zip file of it and install in your computer system.
-
