Please note that the working modes changed by the 0x03, 0x04 and 0x05 commands will not be written

into nonvolatile memory so the working mode will be restored to the former mode before change after

power-off. Users can use the WRITE command to change the working mode of module to standard mode

or low power mode but the sleep mode will be restored to standard mode after next power-on even if the

WRITE command is used.

9. Application Schematic:

The connection schematic between RF1276 and MCU or terminal is shown as below.

The parameter of RF1276'serial port must match with MCU or terminal's (RF1276 has the same serial

port baud rate and parity style with MCU or terminal). Two or more RF1276s in a system should have the

same parameters such as TX/RX frequency, air date rate and RF channel.

Caution: 1. When RF1276 is installed, make sure the antenna is far away from device to enhance the performance.

2. RF1276 should have the same common ground with MCU or terminal. Otherwise it may cause the module

irregular working.

3. When RF1276 works normal, DO NOT touch the module and antenna.
