SerialTransceiver is TTL Serial port "glue" to allow desktop or laptop control of the HAMShield
Commands:
Mode ASCII Description Implemented
-------------- ----------- -------------------------------------------------------------------------------------------------------------------------------------------- -----------------
Transmit space Space must be received at least every 500 mS Yes
Receive not space If space is not received and/or 500 mS timeout of space occurs, unit will go into receive mode Yes
CTCSS In A<tone>; <tone> must be a numerical ascii value with decimal point indicating CTCSS receive tone required to unsquelch No
CTCSS Out B<tone>; <tone> must be a numerical ascii value with decimal point indicating CTCSS transmit tone No
CTCSS Enable C<state>; Turns on CTCSS mode (analog tone) with 1, off with 0. No
CDCSS Enable D<state>; Turns on CDCSS mode (digital tone) with 1, off with 0. No
Bandwidth E<mode>; for 12.5KHz mode is 0, for 25KHz, mode is 1 No
Frequency F<freq>; Set the receive frequency in KHz, if offset is disabled, this is the transmit frequency No
CDCSS In G<code>; <code> must be a valid CDCSS code No
CDCSS Out H<code>; <code> must be a valid CDCSS code No
Print tones I Prints out all configured tones and codes, coma delimited in format: CTCSS In, CTCSS Out, CDCSS In, CDCSS Out No
Morse Out M<text>; A small buffer for morse code (32 chars)
Power level P<level>; Set the power amp level, 0 = lowest, 15 = highest No
Enable Offset R<state>; 1 turns on repeater offset mode, 0 turns off repeater offset mode No
Squelch S<level>; Set the squelch level No
TX Offset T<freq>; The absolute frequency of the repeater offset to transmit on in KHz No
Volume V<level>; Set the volume level of the receiver No
Reset X Reset all settings to default No
Sleep Z Sleep radio No
Filters @<state>; Set bit to enable, clear bit to disable: 0 = pre/de-emphasis, 1 = high pass filter, 2 = low pass filter (default: ascii 7, all enabled) No
Vox mode $<state>; 0 = vox off, >= 1 audio sensitivity. lower value more sensitive No
Mic Channel *<state>; Set the voice channel. 0 = signal from mic or arduino, 1 = internal tone generator No
RSSI ? Respond with the current receive level in - dBm (no sign provided on numerical response) No
Tone Gen % (notes) To send a tone, use the following format: Single tone: %1,<freq>,<length>; Dual tone: %2,<freq>,<freq>,<length>; DTMF: %3,<key>,<length>; No
Voice Level ^ Respond with the current voice level (VSSI)
Responses:
Condition ASCII Description
------------ ---------- -----------------------------------------------------------------
Startup *<code>; Startup and shield connection status
Success !; Generic success message for command that returns no value
Error X<code>; Indicates an error code. The numerical value is the type of error
Value :<value>; In response to a query
Status #<value>; Unsolicited status message
Debug Msg @<text>; 32 character debug message
