Frequently Asked Questions

How do I integrate the TB-03F module with Tmall Genie for voice control?

The TB-03F module is pre-configured for the Tmall Genie Mesh ecosystem. You typically do not need a separate gateway. Ensure your device firmware uses the supported Bluetooth mesh profile and is powered within the 2.7V-3.6V range. The module will be discoverable by the Tmall Genie app for direct pairing and voice command assignment once powered on and in a non-sleep state.

What is the procedure for secondary development and firmware flashing on the TB-03F?

Secondary development requires the TLSR8 series SDK and a compatible SWD/JTAG debugger. Connect to the module's programming pins (typically exposed on the SMD pad layout). Use the Telink IDE or other supported toolchains to compile and flash your custom firmware. Ensure power supply stability during flashing and configure the deep sleep and PWM parameters according to your application's power and control requirements.

What are the power supply considerations and sleep mode configurations for battery operation?

For battery operation, supply a stable voltage between 2.7V and 3.6V. The module draws ≥50mA during active RF transmission. To maximize battery life, utilize the deep sleep mode (0.4µA current) via firmware commands, waking the module via timer or external GPIO interrupt. Ensure your PCB layout includes adequate decoupling capacitors near the VCC pin to handle current spikes during RF activity and wake-up sequences.
