the previous 4Mbit legacy modules the escape characters was fixed and set to “ATMC”, is no longer implemented.
2) Command/Data Mode
The Command Mode or Data Mode will slow down the throughput when the radio looks for the AT commands.
One way to allow minimal overhead transmission burden is to perform all configuration commands, and then place
the radio into the fast data mode.
Note: Byte Gaps and Data Latency – The way Bluetooth is designed and operates random byte gaps of 5 msec to
20 ms are common.
smaller the byte gap delay.
Effective data payload throughput in fast data mode is approximately 250Kbps and 35Kbps in regular data mode
when the AT parser looks at each character for ASCII valid command scripts in the data stream. The radio RX has
very limited buffering so if you do not use hardware flow control and are transmitting further distances you will
quickly overflow the buffer because of RF retransmissions, etc.
When a Bluetooth connection is made the radio modem goes into regular data mode per the power-up factory
default settings.
connection. Basically you can setup the radio so no commands are required to be sent from the embedded side of
the radios UART. This will prevent any software embedded firmware development or testing for legacy systems.

PUT RADIO INTO COMMAND MODE
Function: This sequence is used to force the radio into command mode state. If
the Radio has been placed in Fast Data Mode this command will have no affect
and the typed command will be treated as data. When using this command allow
at least
Format: +++
Return Parameters: If successful an “OK” is returned, or nothing will be
returned if already in command mode or fast data mode.
EXAMPLE:
Note: This command is only required if the module is RF CONNECTED, it has not
effect if the module is not connected or if it is connected in Fast Data Mode.
SET COMMAND MODE ESCAPE CHARACTER
Function: Sets the radio’s escape character, used to put the radio into
command mode.
Format: ATSESC,<ASCII Value>
Parameter:
Factory Default: 43 = “+”
TYPE :
REPLY:
ASCII Value: Integer value of a non extended ACII character
