IPv6 over BLE packets struck and question

[samchang]

hello everyone:

I work IPv6 over BLE example on both Raspberry pi ,this pic is 6LN (CoAP Server)sending IPv6 over BLE packets to 6LBR(CoAP client) and I use tcpdump to sniffer coap port on 6LN。In this BLE packets I transmit coap packet，I know that 600e 8dee 0034 113f is the IPv6 header

but i don't know what 1633 8c21 0034 dbf6 means ? Is it the ble header (like the picture2 of preamble ,access address,data header,payload length information)??

Can anyone provide the packet structure of IPv6 over BLE ? Thanks!!!

I'm not sure I understand. Why would the BLE header be inside the IPv6 packet? BLE is a transport for IPv6 packets, so the IPv6 packets would be inside the BLE packets.

thanks for reply, your mention is right and I will rewirte my question. I'm sure that the IPv6 header is 600e 8dee 0034 113f now .Therefore , i wonder to know that 1633 8c21 0034 dbf6 is BLE header like preamble ,access address,data header...etc ? Am i right? thanks!!!

[samchang]

I thought that BLE header is the outside of IPv6 Packets

If you send IPv6 over BLE the BLE header would be "outside" the IPv6 packets, but you are listening on an ethernet interface? eth0? Not a bluetooth interface? Like bt0?
