Precautions
- address restrictions:
- The first byte of the bus address is prohibited from being
FFOtherwise, it may cause the instruction to fail. - The RF address range is strictly defined according to the protocol, and if it exceeds the limit, it cannot be stored.
- Code Generation:
- After generating the RF code, the data needs to be manually saved, otherwise it will be lost after power failure.
- The wide code mode (F7/F8) is suitable for devices with low receiving sensitivity, such as LV modules.
- Erase operation:
- Whole erase will clear all configurations. Please backup necessary data before operation.
- Do not turn off the power during erasing to avoid damaging the device.
