How to Use Ai Thinker NF-04 Wireless Transceiver Module

To deploy the NF-04, solder it onto your PCB or mount it on a compatible breakout board, then wire VCC, GND and the SPI lines (MOSI, MISO, SCK, CSN/CE) to your microcontroller. Configure the BK2425 registers via SPI to select your desired channel (2.4–2.525 GHz), data rate (up to 2 Mbps RF, 10 Mbps SPI) and transmission power. Implement simple packet framing routines in firmware to send and receive data, and monitor packet loss counters for link quality.

Frequently Asked Questions

What wireless data rate does the NF-04 support?

The module achieves up to 2 Mbps RF throughput using GFSK modulation, while its SPI host interface can handle up to 10 Mbps for register access and data transfer.

Can I read signal strength (RSSI) on this module?

No, the NF-04 does not support RSSI measurement. It provides a simple packet-loss counter to help you gauge link reliability.

How do I set the operating frequency?

You program the operating channel in 1 MHz increments between 2.400 GHz and 2.525 GHz via SPI register writes. Refer to the BK2425 register map in the datasheet for exact commands.
