Steps:
1. When P2.0 (KEY1) with the round hole (GND) the side of its sub with forceps, namely the MCU detects P2.0 for low level, send data then LED1 lights,corresponding to the other side receiving the data, if the data is correct, the LED indicator light flashing.
2. When P3.7 (KEY2) with the round hole (GND) the side of its sub with forceps, namely the MCU detect P3.7 for low level, send data to the machine module LED2 light is lit, corresponding to the other side receiving the data, if the data is correct, the LED indicator light flashing.

Remark:
 If either part through the USB to TTL module and PC connection, open the serial port assistant software, if in accordance with the above operation, in addition to the above LED change effect, a serial port assistant software can display the data received, specific as follows:

 When P2.0 (KEY1) with the round hole (GND) the side of its sub with forceps, namely the MCU detect P2.0 for low level, send data, the other side of the corresponding after receiving the data, if the data is correct, the LED indicator lights flashing.At the same time, the receiver serial assistant software area

Displays the following effects:

20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Remark: 32 bytes, 32 bytes of data, of course, this can be freely defined, transceiver 32 bytes at a time

When P3.7 (KEY2) with the round hole (GND) the side of its sub with forceps, namely the MCU detect P2.0 for low electricity at ordinary times, send data, the other side of the corresponding after receiving the data, if the data is correct, the LED indicator lights flashing.At the same time, the receiver serial assistant software area
Displays the following effects:
37 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Remark: 32 bytes, 32 bytes of data, of course, this can be freely defined, transceiver 32 bytes at a time

Functional test 2: UART equipment (computer) and wireless communication between UART equipment (computer)
Basic function: the bidirectional serial port
Application: application and UART interface equipment, wireless transmission and transmission between the computer and the computer
Steps:
1: install USB to TTL module driver (PL2303HX drive provided free of charge)
2: USB to TTL module and 24 l01 JASK51 - good respectively connected with two computer USB interface (also can use a computer two USB interface test)
3: open the serial debugging assistant software respectively, and choose a serial port number, baud rate defaults to 9600 (when a computer test, two virtual serial port)
4: when any one party sent serial port assistant software after 32 bytes of data, the sending module of LED1 LDE2 are flashing, but after you receive the corresponding receiving module
LED1 LDE2 flashing, also receive complete, at the same time, the assistant software serial port receiving area will display the received data.
If one party sends the following 32 bytes of data data (optional)
01, 02, 03 04 05 06 07, 08 09 10 11 12 13 14 15 16

17 18 19 20, 21, 22, 23 24 25, 26 and 27, 28 and 30, 31 and 32
32 bytes of data, the other party will also receive data (optional)
01, 02, 03 04 05 06 07, 08 09 10 11 12 13 14 15 16

17 18 19 20, 21, 22, 23 24 25, 26 and 27, 28 and 30, 31 and 32
