Frequently Asked Questions

How do I program the Ai-WB2-01S module for a custom application?

You can develop custom firmware using the Bouffalo SDK or Arduino core for BL602. Connect the module's UART_TX and UART_RX pins to a USB-TTL adapter. Use the bkWriter tool to flash compiled binaries. The module also supports AT command mode for basic Wi-Fi and BLE control via serial terminal at 115200 baud by default.

What is the power consumption profile of the Ai-WB2-01S in a battery-powered sensor node?

The module excels in low-power scenarios. During active RF transmission, current can peak above 500mA. However, in deep sleep mode with the RF and CPU suspended, it draws only 12μA. For periodic sensor readings, configure the BL602 to wake from deep sleep, read sensors, connect via Wi-Fi to send data, and then return to sleep to maximize battery life.

Can I use an external antenna with the Ai-WB2-01S module?

The Ai-WB2-01S variant comes with a fixed on-board PCB antenna and does not have an external antenna connector (like IPEX). For designs requiring an external antenna, consider the Ai-WB2 series modules that feature an IPEX connector. The PCB antenna provides adequate range for most indoor applications within a typical home or office environment.

What development frameworks and tools are supported for the BL602 chip on this module?

Primary development is supported via the official Bouffalo Lab SDK, which includes toolchains, drivers, and Wi-Fi/BLE stack libraries for Eclipse or command-line. A community-supported Arduino core for BL602 is also available. For quick prototyping, use the provided universal AT command set over UART to configure Wi-Fi networks and BLE connections without writing firmware.
