There is always hope

@skywatch Correct!

But according to:

https://lowpowerlab.com/forum/rf-range-antennas-rfm69-library/rfm69-hoperf-are-they-semtech-clones-or-not/

And other sources, HopeRF RFM9X are chinese clones of the original semtech sx127X, and these things works using same LoRa.h library from sandeep. So, i guess are practically identical.

Also, i checked MySensors.h compiler definitions, where can be seen 868 and 433 freq are allowed.

So, these radios maybe works...¿!?¿!

I have created and tested PCB's for LoRa on Arduino Nano and Pro mini.
Just open link: https://oshwlab.com/garfius1/lora-pro-mini-easier
And buy some.
You may solder LoRa modules (SX____ or RA-01), and the arduino, and works!

Wiring:
DIO0 (interrupt) to pin3
Reset to pin4
SPI as usual.

Thanks,

Merry x-mas (late)

But i think i posted the wrong section. It might be moved, and this post deleted?

Anyways:

Any idea how to solve the issue?

I am thinking about a thread consuming Hass log, detect the "[mysensors] Connected to Serial<" mesage to send a reset signal to arduino via additional gpio cable.

Thanks in advance.

@pihome Please read full coment before answering.

Hi!

I am trying to set up a lora gateway, and i found a BIG inconvenience. Cannot be used via GPIO serial ports?!¿

Hardware:
-Raspberry pi 3b
-Arduino pro mini 3.3v
-Ra-01 (Ai-Thinker)

Comment:
LoRa node already tested.

Gateway only works if i manually reset the arduino at the time Hass opens the serial port.

IMPORTANT NOTE:
This is normal beheaviour for arduinos with USB-Serial conversor included.

I can try to copy the beheaviour using DTR pin on FT232, but simply don't knoww a way to copy the beheaviour using GPIO serial ports.

Seems Hass waits for MySensors gateway boot message, but gateway is already up since time.

But everithing works well i push reset button on message: "INFO (MainThread) [mysensors] Connected to Serial<..."

So.

Is there any way out?

@nagelc Thaaaanks!
Your answer is valuable to anyone.

@skywatch Correct!

First of all, thanks 4 the great work!

Now, have got a few:

sx1278(ai thinker RA-02)-433
sx1276-868
RFM95W <-- explicitly supported, yeah! like!
RFM98W

And i wonder wether this hardware is fully supported, and wether i can change the default frequencies (868 || 433) to other hardware supported frequencies (RA-02 suppports 410Mhz to 525Mhz).

Thanks 4 the answers in advance.
