- Überprüfen Sie die Stromversorgungslautstärketage (0-3.6V) and ensure it is stable.
- Confirm that the MCU driver code correctly initializes and configures the module.
- Ensure the selected communication channels and data rates match between transmitting and receiving modules.
- Poor Range or Unreliable Connection:
- Check for physical obstructions (especially metal) near the PCB antenna.
- Reduce the distance between modules to test basic functionality.
- Verify that the transmit power is set to the desired level (e.g., 20dBm).
- Check for sources of 2.4GHz interference in the environment (e.g., Wi-Fi routers, Bluetooth devices).
- Try different communication channels.
- Modul reagiert nicht:
- Perform a power cycle on the module and MCU.
- Re-flash the MCU with the latest driver code.
- Ensure the module is not damaged.
