ماژول سریال بلوتوث CC2540 BLE 4.0 XM-10B
Characteristic
Used CC2540 Bluetooth chip, Bluetooth 4 BLE
Default parameters: baud rate is 9600, code is 000000, pairing operation mode from a machine
Module size: 35.5mm x 15.5 mm x 4.0mm (not including the pin)
Working current: the standby 8.5Ma communication: 9mA no dormancy
Bluetooth module <===> MCU
CE/CLR <===> MCU-GPIO not connect (module power switch, high - open, low - close, built-in pull-up resistor, can be suspended)
VCC <===> external power supply (3.0~6V)
GND <===> GND connected with the MCU GND
TXD <===> MCU-RX MCU UART data receiving pin
RXD <===> MCU-TX single-chip UART data transmitting feet (compatible with 3/3.3/5V)
STATE <===> MCU-GPIO can not meet (for judging module running state, with the same LED display)
Note
XM-10B module running (STATE) state
The jump: module in the search or waiting to be connected state
The fixed height (LED Chang Liang): connection has been established and the matching module
The fixed low (LED off): shutdown
From the machine, the baud rate: 9600, N, 8, 1. Pairing password: 1234; if need to place an order when the host mode, please specify
