LoRa FHSS support for STM32WL55JC (E5) module?

[bozgan]

We purchased the STM32WL55JC Long Range Module board for a project. This board includes the LoRa E5 HF module. We are considering using LoRa FHSS in our project. Can this motherboard support LoRa FHSS? Does it support? I couldn't find much information about this on the internet. Please let me know if LoRa e5 supports FHSS.

Welcome to the forum.

Please see the guidelines, How to write your question to maximize your chances to find a solution

In particular, which board, exactly, do you have?

Note that the E5 module is a 3rd-party product:

have you asked Seeed Studio for support?

Hello @bozgan and welcome to the ST Community.

For the STM32WL, it does support the FHSS. We have even an example (the SubGHz_Phy_LrFhss) that run on the NUCLEO-WL55JC1. For your module, it is a Seeed studio product. So, you may want to contact them using their community as suggested by @Andrew Neil.

PS:  the LoRa-E5 module is based on the STM32WLE5JC not the STM32WL55JC.

Best Regards.

https://www.st.com/en/microcontrollers-microprocessors/stm32wl55jc.html I own this product. It has the Lora e5hf module on it. I asked for support from Seeed Studio on this issue, but maybe there is someone on the forum who knows the answer to my question.

The LoRa-E5 module is based on the MCU STM32WLE5JC and not the other way. For your question, I've answered, I think.

Best Regards.

I looked at the FHSS example you told me about. This example only works in TX mode. It sends data using FHSS. I want to listen to these transmitted data with the same model STM32 Nucleo WLE5JC board. Is there an example for this? How can I configure it to continuously listen for the FHSS configuration?
