JDY-18 High Speed Transparent Transmission Bluetooth Module
1.Product brief introduction
The JDY-18 transmission module is based on Bluetooth 4.2 standard, the working
frequency is 2.4GHZ, the modulation mode is GFSK, the maximum transmission power is
0db, and the maximum transmission distance is 60 meters, using imported original chip
design, which supports users to modify the name of the device, service UUID, transmit
power, pairing passwords and other instructions through the AT command, convenient
and flexible to use.
JDY-18 Bluetooth module can realize data transmission between module and mobile
phone or module and module, and can select UART or IIC communication mode through
IO, and through simple configuration, you can quickly use BLE Bluetooth for product
applications.
Make BLE be faster and more convenient in product application.

FAQ
Questions
Question answer
1 ： How does MCU disconnect
Bluetooth
connection
under
connection state?
In the connection state, the PWRC pin is
pulled down, and the serial port sends
AT+DISC to disconnect the connection
IIC can disconnect the memory address:
0X15 writes 0X01 values to indicate
disconnection
2：Can it write data to the module if
the
connection
password
is
incorrect?
No, it can’t. Only the correct password can
write data to the module
3：How much data can the serial port
write at one time?
No byte limit, 100K can be sent once (master
slave communication)
4 ： How fast can the fastest
communication rate be reached?
With mobile phone measured 8K Bytes per
second,
module
master
slave
communication can achieve 115200 baud
rate continuous transceiver, and the rate of
115200bps.
5：After configuring parameters by
serial port or IIC, does it need to be
restarted to take effect?
It is recommended to restart when the
module parameters are set.
6：Parameters of serial port or IIC
configuration, is the power up stored
next time?
After saving, configuring, the next power up
is the last configuration parameter.
7：How to test the deep sleep current
of test module?
It is recommended to connect the VCC and
GND pins to test current.
