LoRa

[Stockers]

Can anyone please point me to any resource to help me understand and develop code to integrate Wemos d1 mini pro to sx1276 based LoRa rf modules.
There are plenty of examples using Arduino but I want to stick with Annex.
I am quite happy with spi interfacing but somewhat struggling to understand how to implement preambles; spreading factor; packet header; CRC and other parameters selectable on the 1276 chip. I have tried reading the sx1276 data sheet and frankly, I get totally lost.
Any pointers to on-line practical help would be much appreciated.

I will try to integrate the LoRa into Annex but I need to buy the module before.

Thanks cicciocb.
I have a couple of E19-868M20S on order from Ebyte, arriving around the end of this month.
I could let you have these on loan for testing if you like. Let me know.

Hi,
I plan to integrate into ESP32 modules, not in the ESP8266 in modules like this one [External Link Removed for Guests]

[Stockers]

OK. It's a pity though because those modules are very expensive for implementing a simple LoRa link.

Hi,
the cost difference between the ESP8266 and the ESP32 is almost zero so it worth to use an ESP32 today.
You'll not obliged to use a module like the one I shown as it will always be possible to use a bare LORA module connected to a bare ESP32 module

[Stockers]

That's good. If it will work with basic esp32 and 1276 based module (ra-02) then that will work for me ok.
What is your time scale for development?

[cicciocb]

No time scale for the moment, I must first buy the module !
