2. Hardware Design Guide

2.1 Smallest System

The ALXC12B embedded a Cortex-M4 MCU, Wi-Fi + BT combo SoC, Flash memory and an on-

board or external antenna, when it’s power on and pulled up the 10K Ohm connected to NRST

(PIN13), it can start to work, shown as below Figure.

Figure 5 Smallest System

2.2 Typical Application

ALXC12B provides multiple host interface and peripheral interfaces such as UART, SPI, I2C and

GPIO. A typical application is ALXC12B to be connected by a customer host through UART or SPI

interface and GPIO for status or application controls. Then the ALXC12B device can connect and

communicate with an AP/router or Bluetooth devices and transmit or receive data with a server.

Figure 6 Typical Application

below. Table 5 GPIO List

2.8 NRST

Under some circumstance, ALXC12B need to be reset to recovery its system. An external signal

needs to be provide to the NRST of ALXC12B. NRST (PIN 13) reference circuit is shown below.

Figure 12 NRST

ALXC12X User Manual

3. Software Design Guide

ALXC12B support two work modes: UART Transparent Mode and ACM Mode.

3.1 UART Transparent Mode

ALXC12B supports serial interface transparent transmission mode when Bluetooth is not used.

The benefits of this mode are a plug and play serial data port, and reduced user complexity. In

this mode, the user should only configure the necessary parameters. After power on, the module

can automatically connect to the default master.

If Bluetooth is used, only ACM mode is supported.

3.2 ACM Mode

ACM (Alinket Controller Message) is a message system and protocol for the communications

between customer host MCU and Alinket IoT controllers. It is developed by Alinket itself and is

applicable to all Alinket controllers.

ACM system works with the host control interfaces between customer host MCU and Alinket

controllers. The messages include host control commands, controller command response, and alarm

events from Alinket controller as well.

Detailed message definition, the implementation of massage Flow Control and Power Save functions

can be found in documents of Alinket Controller Message Specification, Alinket Host Control

Interface Guide (* Please contact your local Alinket sales office or distributors to get the related

documents).

FCC Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This equipment should be installed and operated with minimum distance 20cm between the radiator& your body.

FCC Label Instructions The outside of final products that contains this module device must display a label referring to the enclosed module. This exterior label can use wording such as: “Contains Transmitter Module FCC ID:2AELJ-ALXC12B" or “Contains FCC ID:2AELJ-ALXC12B” Any similar wording that expresses the same meaning may be used.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help.
