AT command
GS-BT2416C1.AT1
Moreover it is possible to store a startup commands sequence directly into flash memory.
The sequence can be long up to 512bytes. If a macro sequence is present, in startup phase,
some OK events are generated, one for every command of the sequence, before the
+READY event.
This behavior can be avoided setting a AT+ECHO = OFF command starting the macro
(avoiding the +READY too). The sequence execution is stoppable changing the state of
GPIO3 in startup phase.
A.3 Interfaces
The module must be controlled by an external MCU using the UART and 2 GPIOs.
● UART: used to control the module with AT commands (COMMAND MODE), or
send/receive serial data to be transmitted over the SPP Bluetooth® link (DATA MODE).
The first time that the module is powered up, the default UART settings are as following
(saved in flash memory):
) Baud rate: (bps) 9600
t(s Data bits: 8
c Parity: None
du Stop bits: 1
ro Flow control: None
te P When these settings are changed by the AT+UARTSETUP command, they are stored in the
le flash memory to be reloaded when the module is powered up the next time.
so ● GPIO1: configured as output. GPIO1 is high when an SPP Bluetooth® link to a remote
b device is present. GPIO1 is low when no Bluetooth® link is present.
O ● GPIO3: configured as input. If GPIO3 is set to high the module switches its mode of
- operation to DATA MODE.
Obsolete Product(s) If GPIO3 is set to low, the module switches its mode of operation to COMMAND MODE.
