AT Command for UHF/VHF Walkie Talkie radio module

Description

The default working mode of the module is wideband, the transmit/receive frequency points are 150.050MHz, and the transmit/receive subcarriers are 67Hz. If no AT command is received to change the parameters, the module will work according to the default parameters. 
In data communication mode, the PTT pin must remain high. 
The normal operation of the module requires a 3.6-4.2V power supply and at least 1A of current. When the PD pin is at a high level, the module works. When the PD pin is at a low level, the module is turned off.

1. After the module is powered on, if no AT command is received, the default working parameters are: Bandwidth: Wideband 
Transmit frequency: 150.050MHz  
Receive frequency: 150.050MHz
Transmit subcarrier: 67Hz 
Receive subcarrier: 67Hz
Squelch level: 2
Scrambler: Off 
Compression: Off
Transmit timeout: Off
MIC sensitivity: 6
Audio output level: 62. In data communication mode, the PTT pin cannot be low level. 3. Working conditions of the module:Recommended DC voltage: 3.6-4.2V, the power supply must provide more than 1A current; 
The PD pin of the module must be high level; 
PD can be used as the on/off control pin of the module.

AT+DMOGRP(old version command AT+DMOSETGROUP ): Set transmit frequency, receive frequency, sub audio, bandwidth, busy channel lockout, transmit power. 

Description: Set frequency, sub audio frequency, power, bandwidth and other parameters.

Format: AT+DMOGRP=RFV,TFV,RXCT,TXCT,Flag,Flag1Example (text input):
AT+DMOGRP=450.02500,450.02500,RR,TT,0,0  (Carriage return/line feed)
Because RR and TT represent sub audio frequencies, they cannot be entered directly in text format; see explanation below. RFV, TFV, frequency values, must be 5 digits after the decimal point.

Example (HEX input):
41 54 2B 44 4D 4F 47 52 50 3D 34 35 30 2E 30 32 35 30 30 2C 34 35 30 2E 30 32 35 30 30 2C 70 06 2C 70 06 2C 30 2C 30 0D 0A Response:
+DMOGRP:0 Success
+DMOGRP:1 Failure

Parameter description:

RFV: Receive frequency value:400.00000-480.00000MHZ (integer multiple of 6.25K or 2K5)
TFV: Transmit frequency value:400.00000-480.00000MHZ (integer multiple of 6.25K or 2K5)
Note: The transmit frequency and receive frequency can be the same frequency or different frequencies (ASCII)
RXCT: DO D1 Receive coding has 2 BYTES. (Hexadecimal number)
Format: BCD code (see explanation below)
The low four bits of RXCT1 are the decimal part. If DEC is not set, fill in FF FF. For example:
67.7 D0D1 data 0x77 0x06 
D023N D0D1=23
80 D244N D0D1=44
82 D023I D0D1=23 
C0 D251I D0D1=51 C2
TXCT: Transmit encoding (hexadecimal number), the same as receive encoding.
Flag: (ASCII)
Bit0 Busy channel lockout (0: Off 1: On) (default off)
Bit1 Wide/narrow band (0: Wideband 1: Narrowband) (default wideband)
FLAG = bit1 *2+ bit0;
Flag1: (ASCII) (Invalid for SR105U model, please set FALG1 to 0)
Bit0 High/low power (0: High power 1: Low power) (default high power)
Default: Transmit/receive frequency 450.05000, sub audio 67Hz.
FLAG1 = 0; 

1. RXCT and TXCT are HEX, not ASCII, so commands cannot be sent directly in text format. For example:Enter the command in text mode on the computer:
AT+DMOGRP=450.02500,450.02500,RR,TT,0,0(press Enter)In the PC serial port tool, switch to send in hexadecimal (HEX) format. The result is:
41 54 2B 44 4D 4F 47 52 50 3D 34 35 30 2E 30 32 35 30 30 2C 34 35 30 2E 30 32 35 30 30 2C 52 52 2C 54 54 2C 30 2C 30 0D 0A
Red represents RR, TT corresponding positions
R R  T TIf the sub audio frequency you need is 67.0, after format conversion, the corresponding sub audio is 70 06; Replace RR and TT with 70 06, so the correct command is:
41 54 2B 44 4D 4F 47 52 50 3D 34 35 30 2E 30 32 35 30 30 2C 34 35 30 2E 30 32 35 30 30 2C 70 06 2C 70 06 2C 30 2C 30 0D 0A
Then click Send.Note:
1. Sub audio setting method:
1) For analog sub audio 
For example: 67.0 67.0 →06 70→ D0 D1= 70 06 
250.3 250.3 →25 03→ D0 D1= 03 25
2) For digital sub audio 
Positive polarity D1 MSB is 8; for example: 
D023N 023→8023→ D0 D1=23 80 
D244N 244→8244→ D0 D1=44 82
Negative polarity D1 MSB is C;
D023I 023→C023→ D0 D1=23 C0
D251I 251→C251→ D0 D1=51 C22. FLAG/FLAG1 setting method
BIT1 BIT0 according to the 8421 BCD code to take the value
FLAG = BIT1 * 2 + BIT0
FLAG1 = BIT1 * 2 + BIT0
For example:
1) FLAG: Bit1 = 1; bit0 = 0
FLAG corresponds to BCD code 2 + 0 = 2; FLAG set value is 2;
2) FLAG: Bit1 = 1; bit0 = 1
FLAG corresponds to BCD code 2 + 1 = 3; FLAG set value is 3; 
2) FLAG: Bit1 = 0; bit0 = 1
FLAG corresponds to BCD code 0 + 1 = 1; FLAG set value is 1;
