Product Overview:

The HM-16 BLE 4.2 Module, equipped with a 2.54mm pinout, is fully compatible with the HM-10 in terms of size and functionality. This module provides a comprehensive pin-out with extensive interface resources and is designed to support ultra-high-speed transmission with BLE 5.0.

Key features include:

Master-Slave Operation: BLE to UART interface with protocols for both BLE 4.2 (HM-16) and BLE 5.0 (HM-18).

Form Factor: Compact dimensions of 13mm x 28mm x 2mm with a 16-pin 2.54mm row pin interface.

Power Efficiency: Standby power consumption as low as 0.1μA, with data transmission rates of up to 5-7KB/s.

Functionality Support: iBeacon, shake detection, small programs, local and remote AT commands, adjustable gain, power, and broadcast intervals. Supports Chinese device names.

Connectivity: The host can connect to any slave device on the market without requiring password pairing. It supports both automatic and manual modes, including self-learning capabilities.

Advanced Features:

Scanning Modes: Normal scanning, iBeacon scanning, and full broadcast packet scanning (V116).

UUID Handling: Supports any UUID and multiple UUIDs in manual learning mode.

Connection Management: Adjustable maximum and minimum intervals for host connection, with support for service and characteristics lookup.

Notification and Indication: Supports Notify and Indicate functionality in manual learning mode.

Data Attributes: Multiple send/receive attributes including WN, WR, IN, NO in manual learning mode.

Upgrade Capability: HM-16 uses the CC2640R2F chip and can be upgraded to BLE 5.0, ensuring high-speed data transmission with a bandwidth of up to 2MBps.
