CC1101/SI4463 Wireless Module UART

From ElectroDragon Wiki

Working Mode

  • M1: Medium Power Saving mode, default mode for EC11.
  • M2: Lowest Power Saving mode, 80ua standby current, high delay 400ms, baud rate only support 1200-4800, data can only transfer 256 bytes per packet due to high delay. Great for lower energry request projects.
  • M3: Full Speed mode, delay down to below 8ms.
  • M4: High Distance mode, the lower baud rate, the longer distance can be reached.
