Hello everybody,

I have bought a Waspmote Gateway with a LoRa module and I want to attach it to a Raspberry Pi and sent everything on a water drone.

The communication is thought to go through a laptop equipped with a Waspmote Gateway+LoRa module, but also, for safety reasons, it should also connect to a RC Transmitter, or remote control.

My 2 questions are:
    1. Will this setup be sufficient for Raspberry Pi - laptop communication?
    2. Is there a way to integrate a LoRa module as a RC receiver in a common RC Transmitter, such as FrSky Taranis or Turnigy?

Any advice is welcomed. Thank you.

minu

Hello minu,
Code:
1. Will this setup be sufficient for Raspberry Pi - laptop communication?

Your drone equipped with RPi+LoRa module will be suitable to send information to your laptop equiped with a LoRa gateway and in the same way your RPi in the drone could communicate with your telemetry transmitter (uart interface maybe) and send telemetry information to your RC through your telemetry receiver.
But we have never do this and we do not have libraries to come to this.

Code:
2. Is there a way to integrate a LoRa module as a RC receiver in a common RC Transmitter, such as FrSky Taranis or Turnigy?

LoRa module uses SPI as host interface, alternatively you can use our gateway to send commands to LoRa module through UART interface (a more friendly interface). Many of moderns RC Transmitters allows programing and communicating with external modules (by SPI or UART) but we do not have libraries to do this. You must do your own libraries. Maybe you can use our libraries as reference.

Regards

Hey dev,

Thanks for the reply.

You mean here that there are no libraries for enabling the LoRa gateway - RC Transmitter communication, or also the RPi+LoRa module - laptop with LoRa?
If the problem is only regarding the first connection, it means that I can communicate with the laptop, by sending and receiving information from and from RPi, through the LoRa module. Therefore I think I may need to create a Arduino-like program on the Waspmote to parse the data, or can I use some Waspmote related API to facilitate this part?

If it supports SPI, then I should be able to listen and send info through the RPI USB onto which Waspmote Gateway is connected?

Understood. But this would mean knowing some signal modulation data of LoRa, which I don't know if it is publicc.

Thank you!

Hello minu,
We do not have got library for LoRa in gateway mode, you must make a manual interface or make any program to do it. You can see a tutorial for LoRa gateway mode in our tutorials:
https://www.cooking-hacks.com/documenta ... eo/#step11
http://www.libelium.com/development/was ... -tutorial/

All you need is the module manufacturer datasheet:

All specifications about LoRa protocol (modulation, channels, etc) are provided by the LoRa Alliance:

Regards.
