STM32-compatible End Devices and Gateways with LR-FHSS Support?

[Mariiian09]

Hi everyone,
I’m currently working on a project involving LR-FHSS and I’d like to know whether there are STM32-compatible end devices and gateways that already integrate LR-FHSS-capable radio chips.

From what I’ve found so far:

• End Devices (sensor/node): They must use a chip from the SX126x family.

• Gateways: They need to be based on the SX1302 or SX1303.

Before I start designing custom hardware, I’d like to confirm whether there are existing commercial end devices or gateways that already include these chips with LR-FHSS support.

If anyone has experience with this or can recommend specific hardware, I would really appreciate it.

Thanks!

Not sure what you mean by "STM32-compatible End Devices and Gateways" here ?

You seem to be talking about off-the-shelf manufactured products - this sort f thing:

Yes?

But these kinds of products would just use standard interfaces - UART, SPI, RS485, CAN, etc, etc - so nothing specific to any particular microcontroller or processor.

Or are you asking if any of ST's chips supports LR-FHSS - to build your own product from component level?

Hi Andrew,
The core of my question is whether STMicroelectronics offers any Development Board (such as a Nucleo or Discovery board) that already integrates an LR-FHSS-capable radio chip (for example, an SX126x) for end-device prototyping.

Additionally, I would like to know if ST provides any development boards that include an SX1302 or SX1303 to experiment with LR-FHSS on the gateway side.

Thanks in advance.

I think you'd probably be better looking to Semtech for such dev boards.

Again, they would have standard interfaces - so MCU-agnostic.

all have a "Dev Kits and Shields" tab ...
