4. Bedienungsanleitung

The RF 2-in-1 Module supports both NRF24 (2.4GHz) and CC1101 (433MHz) communication protocols. It is designed for use with Bruce firmware.

4.1. Selecting Communication Mode

The module features a physical switch to toggle between the 2.4GHz and 433MHz modes. Locate the small switch on the RF module board.

• Anwendung CC1101 (433MHz): Toggle the physical switch to the 433MHz position. Then, navigate to the RF-CONFIG menu in your Bruce firmware and select "RF MODULE -> CC1101 (legacy)".
• Anwendung NRF24 (2.4GHz): Toggle the physical switch to the 2.4GHz position. You can then utilize the NRF24 functions within the Bruce firmware.

4.2. Bruce Firmware Compatibility

The module is fully compatible with Bruce firmware. For advanced configuration and help, refer to the official Bruce Wiki: https://github.com/pcbY/Bruce/wiki.

Notiz: Due to device power limits, 2.4 GHz anti-interference features, and legal regulations, the NRF24 effective range is limited. This module is designed for learning and research purposes only.

5. Fehlerbehebung

5.1. "CC1101 Not Found" Error

If you encounter a "CC1101 not found" or "NRF24 not found" error, this is typically caused by SPI bus timing changes and power management settings in Bruce firmware versions v1.12 and v1.13, which prevent the M5StickC Plus from detecting the module.

Lösung: To resolve this issue, you must flash the Latest Beta Version or Version 1.11 from the official Bruce web flasher. The Latest Beta includes critical patches for SPI initialization and AXP2101 power management, ensuring 100% module recognition and hardware stability.
