XAIO ESP32S3 & Wio_SX1262 connect by their onboard B2B connector #1361

I don't know either of those, and I don't what you mean by B2B connector. The library doesn't care what kind of connector you use, just that you specify the correct SPI and digital pins. |

I have this board on the desk waiting for an attempt. I will give it a go after Christmas. Happy holidays! |

The two boards are connected by a B2B connector. What I haven't been able to determine which pin is which on the B2B connector so I can make sure I'm specifying the correct SPI pins when I instantiate the radio object. I'm getting conflicting information. |

I just want to implement simple LoRa communications between two devices, each of which uses these same pairs of boards connected via the B2B connectors |

The pinout for their board to board connector is on this page and here for the b2b version of the WIO-SX1262 |

Thanks, Walter. I believe I now know what pins to use when I instantiate the radio object. Until now, I had conflicting information about which pins were used by the XAIO ESP32S3. A bit of hallucination by ChatGPT also threw me off course.
Again, thank you!!!

Any chance you can point me to the schematic for the Wio_SX1262 daughter card that plugs in via the B2B connector? I need to confirm where all the pins are for the SPI communications.

Walter,
Again, thank you for your help! However, I’m a bit confused about which connector is which. The ESP32S3 does not show a 30 pin connector and the Wio_SX1262 does not show a 34 pin connector. Can you provide any insight about what I’m missing?
Thanks,
Tom

It's still Christmas so I'm surprised by the speed of this thread, but here's Seeed's pinmap for the OCH-firmware which seems to include a double pinmap: I assume it works, but haven't tried myself yet, so YMMV. |

I'm guessing the "34" pin connector will match the other pins, if you ignore 31, 32, 33 and 34. Their numbering conventions on both connectors are different as well. They should really fix those errors to reduce customers hair pulling.

I’ll try that to match things up. Once again, thank you for your help. I could not find those schematics.

Thanks, Steven. I’ll need some time to absorb all of this, but at least I have some data with which to work!
Merry Christmas

So I'm guessing at the following definitions I need to make in my XAIO ESP32S3 Arduino program: But I still don't know how to assign pins to: |

If you look at the link I shared, you see pin numbers for all pins you mentioned, with IRQ = DIO1 = GPIO1. So through the connector, NSS would be pin 41 for example, while through the pins, NSS would be pin 4. With that information, you should be able to get going I believe. |

(*) Correction: DIO1 only is connected to GPIO1 through the pins, for the connector its value is listed in that link. |

Support for the XIAO ESP32S3 has been added in radiolib-org/RadioBoards@ee471e5. This really was just a matter of copying the pin numbers from the link I shared before. For next time, I advise you check out the resources that are shared with you (such as that link) before making stuff complicated by looking at (admittedly very poorly documented) Seeed schematics. That will hopefully save you some headaches ;) |

I can't seem to figure out how to get a simple transmit and receive Arduino application working with these two boards I recently purchased. Can anyone offer some insight? I imagine it's associated with the use of the B2B connector (I think they call it Sense), but I'm not sure. If it would work better if I not use the connector and breadboard them, please advise.
