+# Control Commands
+
+AACP uses opcode `9` for control commands. opcodes are 16 bit integers that specify the kind of action being done. The length of a control command is fixed to 7 bytes + 4 bytes header (`04 00 04 00`)
+
+An AACP packet is formated as:
+
+`04 00 04 00 [opcode, little endianness] [data]`
+
+So, our control commands becomes
+
+```
+04 00 04 00 09 00 [identifier] [data1] [data2] [data3] [data4]
+```
+
+Bytes that are not used are set to `0x00`. From what I've observed, the `data3` and `data4` are never used, and hence always zero. And, the `data2` is usually used when the configuration can be different for the two buds: like, to change the long press mode. Or, if there can be two "state" variables for the same feature: like the Hearing Aid feature.
+
