Lora SX1280 with FHSS

[HamzaYslmn]

I want to use FHSS using sx1280 and make a two-way custom RC application. But I couldn't find a library or example for this. I need help.

Searching the discussions will explain why there are no examples and why there won't be.

I am the only result with these keywords.

If I use ELRS Airport, it has FHSS support. But using ELRS will be an extra device cost for me.

@HamzaYslmn What leads you to believe SX1280 is capable of transmitting FHSS? There is no mention of this modulation in the device datasheet.

Please read my previous post again - what do you mean by FHSS? Hopping while transmitting a frame, or hopping between frames?

The first one requires support from the radio hardware, which I don't know if SX128x is capable of. The second one is up to the user.

I am looking for a solution that supports 2nd.
Feature 1 should be supported on the hardware side as you said.

In that case it's like I wrote - that's up to you. This library is primarly a driver, it provides interface to the features of the radio hardware (and abstracts away which exact radio hardware you are using). You can call setFrequency between your frames as required by any kind of hopping algorithm you define. Not sure what additional support you need from the library to implement your frequency hopping.

I am currently looking for a pre-written module or library that can handle this. Managing time synchronization is exhausting for me, and I find it quite difficult to grasp.

I'm fairly certain you won't find it, but it's your life - do what you like with it ;)

[HamzaYslmn]

If I can't find it, I'll use ELRS, it supports it anyway :)
