Brief Introduction

DL-CC2340-A and DL-CC2340-B BLE modules are both designed base on TI's SimpleLink™ wireless series CC2340R5 Bluetooth® Low Energy Chip, which uses a 48-MHz Cortex-M0+ kernel, integrates up to 512 KB of flash memory, 36 KB of SRAM, and has up to 26 universal I/O interfaces. Moreover, these Bluetooth Low Energy modules are equipped with a built-in 48MHz 10PPM external high-speed clock, and 32.768Khz external low-speed clock.

The DL-CC2340-A BLE module can use a variety of universal peripherals for all I/O ports of the CC2340R5 chip, which includes UART, SPI, I2C, timer, temperature sensor, battery voltage detection, built-in analog comparator, and 12-bit ADC analog-to-digital converter. In addition, to meet the security requirements of Bluetooth, this BLE module also take security issues into consideration, it also has AES-128 encryption and RNG functions. Customers can use the SDK for secondary development, and embed its complete applications.

The DL-CC2340-B BLE module has a smaller size, but features AT command, which makes it suitable for use as an UART BLE module. The external MCU can be connected to the BLE module through the UART interface to achieve BLE datatransmission. In AT command mode, UART can be used to send commands to modify scan intervals, scan timeouts, connection intervals, broadcast intervals, broadcast custom data, baud rates, etc. The MCU can also send switching commands to the BLE Peripherals through UART, which has broadcast and connection status, and can be connected by the BLE Central, serving as a bridge between the BLE Central and MCU for data transmission.

In terms of RF performance, these CC2340 BLE modules integrate RF balun internally, with simplified RF design, and reduced power consumption. The typical sensitivity can reach as high as -96.5 dBm @ 1 Mbps, and they can also achieve an output power up to +8 dBm. In order to meet the limit standards for RF power in various countries, the power of the BLE modules can be adjusted (ranging from -21 dBm to+8 dBm).

Features
