Repeater shift (separate TX and RX frequencies) #19

Closed ivanpiter closed 6 months ago

ivanpiter commented 2 years ago

Please, add setup for repeater shift (separate TX and RX frequencies).

tomasbrincil commented 2 years ago

Yes, I am into split mode too.

markqvist commented 2 years ago

Thanks for the suggestion! I actually already had this on my list of possible features, so good to know there is interest in it!

markqvist commented 2 years ago

This is coming in the future :)

tomdelta commented 2 years ago

Yes, I need it also !

It will be included in the v2 release of the firmware. There us more info on that here: https://unsigned.io/rnode-a-new-model/

I agree mixed Rx/Tx characteristics could be useful as a low-power repeater/bridge router.

As to V2 release, may I suggest using the Zephyr OS (https://zephyrproject.org/) as dev environment. Zephyr is a Linux Foundation embedded ROS project. It was developed upfront with security and highly constrained SBCs. Zephyr would supports a large number of SBCs including most of the existing RNode boards. Those not currently supported can easily be added. There is a GSOC effort to support the MBED ardruino framework under Zephyr.

I have already looked a bit into Zephyr, and was quite interested in it due to its architecture and nice approach to hardware drivers. The current codebase is not written with Zephyr, but it could still be moved there with minimal pain. It's been a while since I looked at it, so I will give it another look, and see if it makes sense to move there now.

There is a new (GSOC 2022) project ( https://github.com/zephyrproject-rtos/gsoc-2022-arduino-core) that may assist in a "quick" port of the existing V1.x Arduino framework to Zephyr while you work a native V2 port. This GSOC effort is a port of MBED's Arduino framework into Zephyr. I don't know how robust it is to date, but it supposedly works at least at an alpha stage. Zephyr will give you robust OTA FW upgrades (MCUBoot) as well as robust radio support/abstraction.

Thanks for bringing that up, I will look into it!

No takers for implementation. Closing as out of scope for now.
