I am wading in mud and feel like I am sucked into the swamp every step I take.
I want to do a project in Africa (Kenya) where I want to collect data like soil humidity, temperature and air humidity. LoRa seems the solution since I do not have electricity where I need to measure and the distances can be large. Price is obviously an issue.
I am used to work with Arduino’s and ESP32 boards and use them in my house projects and on my farm for all sort of things. I am not a trained programmer but can do enough to work my way through sample sketches and adapt them for my specific purposes.
I use the Arduino IDE but have also installed PlatformIO / Atom since this appearently is a better environment, I am learning how to use it. This runs on my Ubuntu workstation.
I bought a Dragino LG02 gateway and a couple of LoRA32U4II boards as well as two TTGO Lora32 boards with Oled screen. I also bought a LSN50 node since it looked sturdy and I wanted to try an out of the box solution.
So far I achieved the following:
The gateway is up and running and when I power up the LSN50 node I see connections coming in on the LG02 but no sensor data (I hooked up a temp/humidity sensor as per the documentation) When I connect the node to my PC with my UART to TTL adapter and can see that the node is cycling through a number of frequencies but can not issue AT commands as per the manual; my Dutch supplier sent me straight to the factory helpdesk, but they are not helping.
I have the TTGO Lora32 talking to each other (one sender, one receiver) with a DHT22 sensor but can not get a sketch running on them to link them to TTN. I have tried numerous sketches found on the Interwebs…
I can not get the LoRa32u4II boards to work; have soldered on the wire to pin 6 etc. I have succesfully fried one by reversing VCC/GND. This was a lesson to stop trying after a certain amount of hours.
As you may understand I am getting pretty frustrated and hope that someone can point me in the right direction.
thanks for reading,
