WebESP32 Classic Bluetooth has two protocols, namely A2DP and SPP. The maximum MTU Size setting of BT A2DP (default) is 1008 bytes, of which the header occupies 12 bytes and the actual amount of data transmitted by the application layer is 1008 - 12 = 996 (bytes); the maximum MTU Size of BT SPP (default) Set to 990 bytes.
