13. 1 Fast Data Mode The drawback to this is that once in fast data mode there is limited ways to get out of it like CPU reset power down or strobe PIO 4 on the radio The advantage of this mode is that the data being sent does not have to be evaluated or processed for AT commands and will allow for a faster effective data throughput of around 200Kbps To verify you are in fast data mode type lt cr gt it will pass directly through the UART because the AT Command parser is off Else the lt cr gt will be accepted because the AT Command parser is still on and returns OK On the previous 4Mbit legacy modules the escape characters was fixed and set to ATMO is no longer implemented 2 The different operation modes are explained in the next table below The Command Mode or Slow 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 Put Radio into Command Mode when Bluetooth connected This sequence is used to force the radio into command mode state If the Radio has been place 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 100ms delay before sending next AT command 7173 S Havana Street Suite 600 Englewood CO 80112 Tel 303 957 1003 in
