Command AT+DTMCFG 11 n
Values for n
0 (Disabled), 1 (enabled)
Default 0
Command AT+DTMCFG 4 n
Values for n 0 (Disabled), 1 (enabled)
Default 1
Command AT+DTMCFG 5 n
Values for n 0 (Disabled), 1 (enabled)
Default 0
This will be ignored if AT+DTMCFG 5 is set to 0 (which is the default). If a bit is set then the bit number corresponds to the
GPIO number which is enabled.
Command AT+DTMCFG 6 bitmask
Values for n 0x00000000 to 0xFFFFFFFF (bit 0 is the lowest significant bit)
Default 0
This will be ignored if AT+DTMCFG 5 is set to 0 (which is the default). If a bit is set then the bit number corresponds to the
GPIO number will have the direction input when the bit is 0 and an output when the bit is 1.
Command AT+DTMCFG 7 bitmask
Values for n 0x00000000 to 0xFFFFFFFF (bit 0 is the lowest significant bit)
Default 0
This will be ignored if AT+DTMCFG 5 is set to 0 (which is the default). If a bit is set then the bit number corresponds to the
GPIO number will have the output set to this value if DTMCFG 7 was used to set the direction as output.
Command AT+DTMCFG 8 bitmask
Values for n 0x00000000 to 0xFFFFFFFF (bit 0 is the lowest significant bit)
Default 0xFFFFFFFF
