SCO / eSCO Audio Link

BTM modules provide an AT command to establish an SCO / eSCO audio connection between a pair
of BTM modules (or BISM2). This enables the user to create bidirectional audio links independently
from a particular Bluetooth profile. The only prerequisite is the existence of a Rfcomm link (serial
port profile) between the modules. If this link doesn’t exist, it can be created using
AT+SPD<BdAddr>. Please refer to pg. 29.

A SCO/eSCO link is intended for bidirectional transmission of speech. The sampling rate is fixed to 8
kHz, meaning a usable bandwidth of 3.5 kHz.

For SCO there are 3 packet types defined in the Bluetooth specification [1]: HV1, HV2, HV3. Each of
them occupies one slot. They differ in the level of bit error checking. It is recommended to enable
all three packet types for SCO links. This will pass the final decision down to the baseband. There is
no retransmission of erroneous SCO packets.

For eSCO and basic data rate, there are 3 packet types defined in the Bluetooth specification [1]:
EV3, EV4, EV5. EV3 occupies one slot, EV4 and EV5 can occupy up to three slots each. They differ in
the level of bit error checking. It is recommended to enable all three packet types for eSCO links.
This will pass the final decision down to the baseband. eSCO packets involve a CRC code and
retransmission of erroneous eSCO packets.

Packet types and link types (SCO or eSCO) are negotiated on link setup. A BTM can accept either
incoming SCO or eSCO links (S register 584), but not both SCO and eSCO at one time. If the initiating
side requests an unsupported link type, the audio link will fail. The initiating BTM module is
supposed to request the remaining link type in that case.

Table 3-23 lists all AT commands and S-Registers for SCO/eSCO links.
