Specifying SPI pins, is it possible to do this?

[aelmaker]

Hello. I have been trying to configure the sx1262 (ebyte E22-900) and esp32 module for several days, but I have a problem to configure the SPI pins. My questions are: Will the library work on ESP32-C3 (RiscV 1-Core)? How to change the settings of pins of a regular ESP32 (wroom, nodemcu). Since it is possible to use 2 SPI (VSPI, HSPI). I am using given examples in Arduino IDE: _RadioLib\examples\SX126x\SX126x_Transmit RadioLib\examples\SX126x\SX126xReceive

I've tried specifying like this:

SPIClass *loraSPI = new SPIClass(HSPI);
SX1262 radio = new Module(5, 4, 16, 17, *loraSPI);

but it doesn't work as there is no SPIClass class. Please tell me how to specify the SPI pins?

Assuming the ESP32 Arduino core supports it, it should work out-of-the-box.

but it doesn't work as there is no SPIClass class.

SPIClass is a part of the Arduino framework, so it should always be present. Please fill in the issue template. What is the output when you try to compile?

Hi, I solved it in the following way. Connected by force: #include Specified settings

SPIClass mySpi (VSPI);
SPISettings spiSettings (2000000, MSBFIRST, SPI_MODE0);
SX126x radio = new Module (5, 4, 16, 17, mySpi, spiSettings);

And also in the setup () block I forcibly set mySpi.begin (); For me, it still remains a mystery how to set specific pins for SPI lines.

Thanks for answers! I also have a question about setting the channel number, netid (device id) and key in Lora mode? I studied all the commands, but I did not find such commands similar commands not on one of the levels of the library

include is already being done by RadioLib, your Arduino IDE seems broken. Again, please fill in the issue template and post the original error message(s).

I also have a question about setting the channel number, netid (device id) and key in Lora mode?

I'm assuming you're referring to LoRaWAN - that is not supported by RadioLib.

I have already solved all the questions, thank you very much. There are no more mistakes. I am interested in the ability to understand who sent a message between several devices with one sync word and the sending takes place on the broadcast port 65536, maybe I do not quite understand how this works in Lora, but does the library allow me to understand this

[jgromes]

I don't know what "broadcast port" you're referring to - LoRa packets do not have the concept of port.

[aelmaker]

I mean radio.set Broadcast Address (0xFF); Is it possible to find out which device sent the message without indicating this in the load message?

[jgromes]

That only applies for FSK packets. And no, it's not possible, you would have to include that information in the payload. The address is just a simple filter that the radio applies.

I follow your code with LLCC68,but get a error:-20; the debug message:[SX1262] Initializing ... failed, code -20
