Readout of a register
Syntax:
ATSx
<CR><LF>
[x = 1, ...,16 register to be read]
Return :
value stored in the register if the command sintax is correct followed by <CR><LF>.
Register value is given digit after digit as ASCII characters.
Example:
‘16’ is given as the sequence of ASCII characters 0x31,0x36, corresponding to digit ‘1’ and ‘6’.
Same procedure must be applied in case of writing a new value in a register.
Writing of a register
Syntax:
ATSx=Y
<CR><LF>
[x = 2, 3, 4 register to write on, y = value to add]
Return:
as described in 'Return values'
All values stored in the registers will be lost when the module is turned off, unless the changes are saved in
microcontroller EEPROM memory by means of the specific command ATWR: in this case the saved values
will be active even if the module is turned off and then on.
Command to save registers value in EEPROM
Syntax:
ATWR
<CR><LF>
Return:
as described in 'Return values'
Command to quit command mode
Syntax:
ATCC
<CR><LF>
Return:
as described in 'Return values'
Command mode exit occurs, even without ATCC command, automatically after 10 sec. of idle state, or after
the command ATWR.
3. NORMAL
Enabled once the XTR-8LR-USB is inserted in a PC USB port and also once it comes back from
“Command Mode”. Normal mode is shown by the red led blinking each three seconds. The device is able to
receive data thought RF and through Usb and forward consequently. The device is always in reception and it
enters in transmission once it receives data though Usb.
The way the
store & Forward
mechanism works is described by couples of sequence operations:
Store from UART on unit A /Forward to RF buffer on unit A/ RF TX unit A
RF RX unit B/Forward to UART output on unit B [Picture 4]
