<![CDATA[LoRa (433 old) LoRa V1.1]]>weiß jemand wie man ein neues V1.1 LoRa Modul so jumpert
das es mit dem alten Modul kompatibel ist, der Support schweigt sich aus und hat scheinbar auch keine Ahnung

ok, now I understand - thank you for clarifying about the closed source M5Core firmware.

BTW: for RST and IRQ you could set no jumper and then solder a wire each to the desired GPIO on the M5Stack bus connector.

Thanks
Felix

Then I'll convert the old modules to an SMA connector. The software is called APRSCube, by the way, and it was a good advertisement for M5Stack modules...
Thank you very much.

I am confused. Your own firmware, the one you write for your M5Core (which talks to the LoRa module), is closed source? How come? Are you not writing your own firmware?

I already wrote that it is not possible to jumper LoRa V1.1 the same as the older one, please see my previous post.

MOSI, MISO, SCK and CS/NSS can be setup to use the same GPIOs, however RST and IRQ cannot be jumpered to be the same.

So in conclusion: If for whatever reason the firmware running on M5Core (controlling the LoRa module) cannot be modified then it is not possible to substitute the older LoRa module with the new one.

Thanks
Felix

I'm sorry, but your answer is not helpful. How do I have to jumper the V1.1 board so that it works like the old one? I've already seen the graphics, but they're a confusing mess.

reading your other post, I think you already figured that out yourself. It's not possible to jumper LoRa V1.1 so the same GPIOs are used as it were for the older LoRa module.

Both LoRa modules use the same GPIOs for MOSI (23), MISO (19) and SCK (18). However RST and IRQ cannot be jumpered the same; CS/NSS can be jumpered the same.

LoRa (433 old): RST(26), IRQ (36), CS/NSS (5)
LoRa V1.1: RST(25/13), IRQ (35/34), CS/NSS (0, 15, 12, 5)

Note: GPIO numbers above are for an M5Core (Basic).

Please also see schematics here and here.

Just curious. What is preventing you from modifying your firmware to use the GPIOs of the newer LoRa module?

Thanks
Felix
