Thread Router Multi-pan Communication #9770
-
|
Hello all, I'm pretty new to OpenThread and would like to seek some guidance and clarification on this one: I'm currently working with several Minimal Thread Devices (MTDs) and a Thread router. Is it possible to configure the router to support multiple PAN IDs simultaneously? If so, is there any relevant documentation or examples that I can refer to? Thanks in advance! |

To support multiple Thread networks on a single Thread router, ideally the Thread router will have multiple Thread radios, one to support each Thread network. Typically, a Thread radio can only be listening on a single channel, so having multiple Thread radios allows each Thread network to operate independently, including on different channels. |

How can I make one radio to launch multiple instances? I see some flags like OT_MULTIPAN_RCP=1 OT_MULTIPLE_INSTANCE=1, but I am not able to figure out how I can configure this. I tried building the ot-rcp binary using the following command ./script/build nrf52840 USB_trans -DOT_BOOTLOADER=USB -DOT_FTD=OFF -DOT_MTD=OFF -DOT_RCP=ON -DOT_MULTIPAN_RCP=1 -DOT_MULTIPLE_INSTANCE=1 I converted the binary to hex and converted it to uf2 format to flash the radio dongle. But somehow after flashing my nrf52840, it it not getting recognized as a USB in my raspberry pi 3. Could you please guide me, how I can configure my nrf52840 dongle to support multiple instances? Also is there a way that I can also simulate this? Thanks in advance for the help. :) |

Hi, Were you able to successfully establish the network where multiple PAN-IDs are handled on a single router in openthread? |

Are you looking to support multiple Thread networks with a single 802.15.4 radio? We generally recommend using multiple 802.15.4 radios, especially in cases where the different networks are operating on different channels. |

Do you think, I mean is it possible to configure multiple pan-ids on a
single router? If I change the open thread code?

Each Thread network has its own PAN ID. Multiple Thread networks can be done by having multiple OpenThread instances. |

But can I configure multiple pan-ids(ESP32) on a single router (single open
thread network) ?

As mentioned in above, each Thread network has its own PAN ID. It is possible for a single device to support multiple Thread interfaces, just like supporting multiple Ethernet, Wi-Fi, or Cellular interface. Also, please respond to the original thread, rather than creating new suggested answers. |

@orangenlimer159 @Raj-mac24 The multipan feature on ESP32 802.15.4 SoCs allows a device to operate in multiple 15.4 PANs simultaneously. However, all PANs must be on the same channel. A single OpenThread network has only one PAN ID, but it is possible to support multiple Thread networks using multiple OpenThread instances. For assistance with your specific requirements, please contact us via Contact Us. |
