AT command

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.
Interfaces
The module must be controlled by an external MCU using the UART and 2 GPIOs.
●
When these settings are changed by the AT+UARTSETUP command, they are stored in the
flash memory to be reloaded when the module is powered up the next time.
●
●
If GPIO3 is set to low, the module switches its mode of operation to COMMAND MODE.
UART: used to control the module with AT commands (COMMAND MODE), or
send/receive serial data to be transmitted over the SPP Bluetooth
The first time that the module is powered up, the default UART settings are as following
(saved in flash memory):
GPIO1: configured as output. GPIO1 is high when an SPP Bluetooth
device is present. GPIO1 is low when no Bluetooth
GPIO3: configured as input. If GPIO3 is set to high the module switches its mode of
operation to DATA MODE.
