Magic Packet sender

Use the rail_soc_simple_trx_std example to send magic packet. By default example sends/receives 802.15.4 frame, so you don't need to modify frame format.

startup

The addresses (Src and Dst) and the PAN ID can be customized via CLI commands. If you want a complete list of the available commands issue the help command.

startup

Once your packet has been customized, use the send command to send the packet and wake-up the RCP.

Testing the magic packet detection

Follow this sequence (tested on BRD4166A) to validate the behavior:

  1. Start the OTBR and create a Thread network. To do so, follow this guide

  2. Retrieve PanId of the created Thread network.

    user@ubuntu:~$ sudo ot-ctl dataset active
Active Timestamp: 1
Channel: 15
Channel Mask: 0x07fff800
Ext PAN ID: 1111111122222222
Mesh Local Prefix: fd47:8922:96ec:b4d0::/64
Network Key: 00112233445566778899aabbccddeeff
Network Name: OpenThreadDemo
PAN ID: 0xcafe

Done
  3. Press Button 0 on BRD4166. After, pressing button, RCP will be sensitive to the wake-up frame if it matches magic packet filter.
  4. You can now disconnect UART RX/TX from Host side. BRD4166 needs to stay powered. (You can use Mini Simplicity connector to maintain powering)
  5. On rail_soc_simple_trx_std side, use CLI to set SrcAddr = 0xFFFF, DstAddr = 0xFFFF, and PanId to the PanId retrieved above using CLI
  6. Finally send a packet with the rail_soc_simple_trx_std. Red led of BRD4166 should switch on.
