Wireless HC-11 433 To Serial C1101 Long Range Module

FEATURES:

1. 3.4mA silent current ultra-low-power
2. Long distance, using the distance 1 ~ 40M. (Less than 1M, the module does not work)
3. Support 3.3V ~ 5V wide voltage
4. Supports serial pass through mode, replace the serial line (half duplex)
5. You can set the frequency, such as dozens of commands, automatic filtering
6. Module size: 27.8mm × 14.4mm × 4mm.
7. For network design
8. The module supports software upgrades
9. Communication baud rate: 9600
10. The wireless communication channel: 001

SPECIFICATIONS:

Mode: FU1

1. Idle current: 3.5mA
2. Transmission delay: 20mS
3. Loopback test 1: 31mS
4. Loopback test 2: 31mS

Note: The loopback test delay means, short connect TX and RX pins, send serial data to another module, from the beginning to another module TX pin return to the data.

AT COMMANDS:

Enter AT command mode in two ways:

The first: After connect with 3.3V, then pull low the fifth pin (always low), the module is in the AT command mode, pull up means exit command mode.
The second: Disconnect power, pull low the fifth pin first and then power on again, after 1S enter the AT mode, pull up means exit command mode.

INSTRUCTIONS:

1. AT:

• Send this command will return OK characters.
• Example: Send AT return OK

2. AT + V:

• Module returns version information. 
• Example: Send AT + V return HC-11_V0.0

3. AT + Bxxxx:

• Set baud rate to xxxx. This value may be 2400, 4800, 9600, 19200, 38400, 57600, 115200.
•  Example 1: send AT + B4800 returnsOK-4800   
•  Example 2: send AT + B115200 return OK-115200

4. AT + Cxxx

•  Set the communication channel. From 001-127 optional.
•  Example: Send AT + C058 returns OK-058

5. AT + FUx

•  Switching serial transparent transmission mode. The value of x from 1 to 4 optional.
•  Example: Send AT + FU1 return OK + FU1
