GatePi 4Channel
GatePi is a low-power consumption data transmission board, that comes with an onboard CH340 USB TO UART converter, Voltage Level Translator(74HC125V), E22-400T22S/E22-900T22S SMA antenna connector that covers 433/868/915 MHz frequency band, 4-Ch Relays, IPEX antenna connector, LoRa™ Spread Spectrum Modulation technology with auto multi-level repeating. GatePi is developed to enable data transmission up to 5 KM through the serial port.
Pin Mapping
DIP(Slide) Switch
It is four way slide switch used select direct cummunication with LoRa module or communication through RP2040 via micro-USB. The 1 and 2 should have in "ON" postion, 3 and 4 should be in "OFF" position for working with our Example codes.
Code
- You see the "main.py" file. you need to save this file inside GatePi(RP2040)
- Rest the two folders is of Application(GUI), one is of window other is of raspberry pi
- Window application->open the app and follow the below instruction, you need to connect one of them Pi Lora Hat or PICO Lora Expansion and RangePi(transmitter)
- Raspberry pi application->open "raspberry pi GUI" folder.run "Lora Home Automation.py" file, before this, you need to put Pi Lora Hat(transmitter)
rangepi__transmitter_app_control.py - save this code as main in RangePi and connect RangePi to laptop, open application and control GatePi(Only For RangePi)
You can control GatePi with the help of raspberry pi GUI, or you can also control through pc via GUI
In windows, you can use PICO Lora Expansion, Pi Lora Hat and RangePi
GatePi Instruction Manual
For manual download the GitHub directory GatePi, in this directory you see "GatePi instruction manual.pdf" open that manual
- In this manual you see:-
- how to setup GatePi
- How to use "LoRa Home Automation Application(App)
Working With GatePi 4Ch
For working with this board you will need two or more than two loara product, it can be same products or may be our other LoRa products to establish the communication between them.
-
***The "main.py" is the reciever example code for controlling 8 relays. This code should be saved in RP2040 of GatePi 8ch so that when it recieve data from transmitter it will operate realys one by one according to data recieved at this end.
-
***The "Transmit.py" file is the code for sending the data for the purpose of controlling relays of GatePi. This code can be saved in any of our LoRa devices(such as RangePi) to send data. It will send "1relay1" at a fix interval of time to operate "relay-1" and so on for other relays, you can replace this by any keywords you want but this should be change in reciever code also.
Our Other LoRa Products
- GatePi 4Channel*
- GatePi 8channel
- RangePi(USB Dongle)
- LoRA HAT for RPi
- PICO LoRa Expansion
You will simply need to make one device to work as reciever and another one is as a transmitter. So that you can communicate to each other and this can be done with any of our LoRa products mentioned above. For working with our other products please follow the below link:
- GatePi 4Channel* (Itself)
- GatePi 8channel https://github.com/sbcshop/GatePi-8CH
- RangePi https://github.com/sbcshop/RangePi
- LoRA HAT for RPi https://github.com/sbcshop/Lora-HAT-for-Raspberry-Pi
- PICO LoRa Expansion https://github.com/sbcshop/PICO-LORA-EXPANSION
Note: Every time you choose the mode of transmit device the transmit code of that device should be run in it and reciever code will always same.Note: Every time you choose the mode of transmit device the transmit code of that device should be run in it and reciever code will always same.
Lora GUI For Configuration (run with the help of GUI)
For this, you need to use Lora onboard USB
Go to the Lora GUI folder, and run the LORA_GUI.py file. from this file, you can configure the Lora and you are able to transmit, receive the data (eg: baud rate, channel etc) Follow the steps to configure the Lora module:-
Step 1: Setup lora in configuration mode, for this you need to short M0 and open M1 as shown in figure. In case of GatePi-4Ch M1 and M0 is GP2 and GP3 respectively. You simply have to remove GP2 jumper for configuration mode(Below is the refference of LoRa HAT).
Step 2: Open lora GUI
Step 2: set the COM Port and Baudrate
Step 3: For COM Port go to Device Manager, before this first you need to connect the Lora module via USB cable
Step 3: Write the right COM Port in the GUI,then press connect button
Step 3: Press read button to see the device configuration which lora already have
Step 3: Write the values which you need to configure, for eg: i configure channel and baudrate, after that press write button
Step 3: Restart the GUI, set baudrate and port, then connect and press read button
