1, FUN function gear switch:
A file: KISS mode, do not send any beacon, does not respond
to manual PTT control.
B file: hand microphone PTT linkage hands meters the call is
over release PTT, automatic trailing transmit APRS data.
C file: Intelligent GPS beacons, GPS beacons transmit automatically
depending on the speed, course.
D profile: timing of GPS beacon, according to the time set emission
GPS beacon
E file: DIGI relay mode, receiving and forwarding data in line with
set conditions.
Either stall mode when not connected to GPS, GPS positioning is
not valid data, will not transmit GPS data beacon
Either stall mode, do not affect the RF decoding (decoding at any time),
will not affect Bluetooth / Serial send and receive data.
Either stall mode, GPS always in communication, GPS status can be
obtained by GPS lamp.
2, LED indicator:
GPS status indicator:
- Off: no connection GPS
- Slow flashing: GPS positioning is not valid data, automatic
identification 4800/9600 rates, the state of communication errors
- Solid: GPS has been positioned, the output of valid data
MOD: Indicates PTT IN state, when PTT is pressed, lights,
release the extinguished.
POW: standby, interval 1S flashes to indicate that the board
is running normally.
RXD: Radio receiving the complete data, synchronized flashes
after successfully decoded with the Bluetooth / serial output data.
TXD: When the station transmits data shiny shiny.
STU: Bluetooth status lights, regardless of the TNC, Bluetooth is
not connected, flashing after the connection Always.
TNC power-up or reset, the above LED (except STU) blinks several times,
indicating successful initialization, and for detecting LED.
Instruction Set Description:
Note: All settings command should + Enter (ENTER key).
After setting the parameters, the board will reset and the
output of all parameters.
Instruction only three.
Command 1: AT + DEMO =?
Description: Sets the recovery board defaults.
Command 2:! GPS + BEACON = BG1WPR-9,0,, r, GPS BEACEN, 1,60!
Description: Sets the beacon callsign, ID, relaying path, type, icon,
custom information with voltage report, the timing beacon time.
It must be seven parameters, separated by a comma in the middle.
The default data analysis: BG1WPR-9, 0,, r, GPS BEACEN, 1, 60
1, GPS + BEACON = fixed character
2, BG1WPR-9 beacon callsign, default callsign NOCALL, capital, up to six.
Beacon SSID, default 9, the parameter value range 0-15.
ID call sign and between the symbol "-" separated.
3,0 beacon transmitted data set contains WIDE1-1 or WIDE1-1, WIDE2-1 relayed path information.
0 = No path
1 = WIDE1-1
2 = WIDE1-1, WIDE2-1.
Default = 1, which contains WIDE1-1.
4 ! It indicates the type of character, a word of fixed length,
generally do not change. To change the reference APRS protocol manual.
5, r the icon that represents the style of the map display on the server,
a fixed-length word, referring to "APRS icon set" Change.
6, GPS BEACEN! Represents the custom message up to 80 characters, English.
If you want to write PHG information, fixed form. Note 1.
7,1 beacon information section at the end is inserted TNC voltage report.
1 = yes, 0 = no.
8,60 timing of beacon transmission time, range: 0-65535 seconds,
when set to 0, it does not send beacons. TNC effective the timing beacon mode.
Note 1: Information section of the top grid, the first seven characters,
when filled PHG information, the server will automatically recognize and display.
Command 3: AT + SETUP = 2,2,1,0,0
Description: Sets the TNC, it must be five parameters, separated
by a comma in the middle.
Chapter 1: PTT transmission delay time, unit 250ms, the parameter
value range 1-9, that 250ms-2250ms. Default 2, namely 500ms.
Chapter 2: packet transmission interval, 50MS, default 2, namely 100ms.
Chapter 3: DIGI mode when receiving data containing WIDE1 path forwarding,
0 = disabled, 1 = enabled. Default = 1, which is enabled.
Chapter 4: DIGI mode when receiving data containing WIDE2 path forwarding,
0 = disabled, 1 = enabled. Default = 0, which is closed.
Bit 5: Allow forwarding inbreaking name, 0 = disabled, 1 = enabled.
