Frequently Asked Questions

What development environments are supported for programming the Ai-WB2-12S module?

The module supports secondary development using the official BL602 SDK, which is compatible with Windows and Linux operating systems. You can write firmware in C using the provided toolchain. For quick prototyping without coding, you can use the universal AT command set via a UART connection at the default baud rate of 115200 bps to configure Wi-Fi and BLE connections.

How do I power the Ai-WB2-12S module and what are its sleep current specifications?

Power the module with a regulated supply between 2.7V and 3.6V, ensuring it can deliver peak currents of at least 500mA during RF transmission. For optimal battery life, utilize the module's sleep modes. The deep sleep mode consumes approximately 12μA, while light sleep modes offer a balance between responsiveness and power savings, making it suitable for periodic sensor reporting applications.

What is the default antenna configuration and can I use an external antenna?

The module comes with an integrated PCB antenna etched onto the board, which is sufficient for most short to medium-range applications within the 2.4GHz band. The design does not include a standard external antenna connector like IPEX or SMA. For projects requiring an external antenna, you would need to modify the RF layout on your carrier board, ensuring proper 50-ohm impedance matching to the RF pad.

What security features does the Ai-WB2-12S module offer for Wi-Fi networks?

The module's BL602 chip includes a hardware cryptographic engine supporting AES-128/192/256 encryption, SHA-1/224/256 hashing, and a True Random Number Generator (TRNG). For network security, it supports WPA3, WPA2 Personal/Enterprise, WPA, and WEP protocols. Secure boot with ECC-256 signature verification ensures firmware integrity, making it suitable for commercial IoT products requiring robust security.
