tool_calls: name: unpack_data
arguments: tag: D5
type: string

tool: D5: Usage: brfpatch INPUT OUTPUT

	Generates bluetooth firmware

INPUT: Bluetooth script in ASCII format.
       For TI BRF chips this can be generated from .bts files using the TI Bluetooth
       script pad to save as .txt. This txt file can be used as input.
       Alternately, run strings on the .bts and manually edit to change decimal
       arguments into hex of the appropriate number of octets.
       FORMAT: Send_HCI_xxxx OPCODE DATA1 DATA2 DATA3 ...
       where OPCODE, DATA1 etc are one of:
       0x12          (1 byte)
       0x1234        (2 byte)
       0x12345678    (4 byte)
