以前購入したBLE用スニファの動作が安定しないので、Raspberry Pi-Zero-WでBLEパケットをキャプチャしてみる。
使うツールは tshark らしい。
hcitool を使うとBLEデバイスをスキャンしたり多少通信できるようなので、、まずはhcitoolでスキャンしてみる。
hcitool leinfo 30:AE:A4:CC:4D:1A BLELibTest123
ESP32上にはBLEサンプルを動かしていて、アドバタイズしているので、それを見つけたようである。
tsharkでキャプチャした状態で、hcitoolでlescanを実行、いろんなデバイスのアドバタイズが取れるのだが、ESP32のデバイスは以下のパケットだと思う。
# tshark -i 4 -V &
# hcitool lescan

RSSI: -77dBmラスパイについているBLEを使って送受信したパケットはキャプチャできても、他人同士で通信しているパケットは取れないようである。どうやら、(promiscuous mode としては動かせないような。。)だから、ノートPCとESP32上のBLEとの通信は、ラズパイではキャプチャできなさそうである。。うーん、道は険しい。
■メモ
BLEは一度ペアリングすると鍵情報を記憶して、次回から鍵交換を省略する（と理解）。ラスパイの場合も一度ペアリングしてしまうと次回はペアリングパケットが飛ばない（多分）。鍵情報を削除するには以下ディレクトリ配下のcacheを消す
/var/lib/bluetooth/
もしくは、bluetoothctlコマンドで一旦connectしてdisconnectする
tsharkでパケットキャプチャしながら、bluetoothctlでconnect/disconnectを行った。
その時に流れているパケット。これを読み解ければconnect(pairing?)が分かるはず
$ sudo tshark -i 4 -V
Running as user "root" and group "root". This could be dangerous.
