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!!!
