TI CC2540 Bluetooth Low Energy 4.2 (BLE) Module XY-MBT40A2

The XY-MBT40A2 is a mighty, highly flexible, ultra-low power Bluetooth® 4.0 module based on the TI CC2540 SoC solution, with an 8051 MCU.
Built-in 256KB Flash, 8KB SRAM, rich, configurable peripheral interfaces, and high-performance low-power Bluetooth RF, transmit power adjustable from – 23dBm to +4dBm, receive sensitivity of -93dBm.
In addition, the module also integrates 32MHz, 32.768kHz crystal oscillators and RF PCB printed antenna, industrial-grade design, RoHS process, and half-hole pins for easy production processing.

Software Features

The device can be connected to any BLE-enabled cell phone through HID protocol in the system’s background when it is shipped.

Support allowlist set allows the device to connect and put the device into allowlist by serial command, support command to clear a device in the allowlist.

Support serial AT command: Baud rate modification, Name modification, Allow the device to connect, Get allowlist information, Clear allowlist.

Serial port output module status: connection success, connection failure, disconnection.

The module currently connected device authentication notification pin PIN19(P0_7): not connected (high level)/connected (low level).

Module wake-up pin PIN15(P1_3) Function: Wakes up the module on the falling edge and disables the module from going to sleep during the low level; this pin should be pulled low during the MCU sending data to the module, the pin is internally pulled up by default.
