away from the module according to the strength of the interference.If necessary, appropriate isolation and shielding

can be done;

If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is



still a risk of damage);

The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure



that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good

antenna extension cable to extend the antenna to the outside;

The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly



weakened.

Programming

It can complete the wireless data transceiving by operating its control register and transceiving buffer. Please refer



to the latest CC1101 data sheet for the timing operation of module register.

GDO0 is a general purpose I/O port，see CC1101 user manual；



GDO2 is generally configured as an IRQ-like function, or not connected. SPI query mode can be used to obtain the



interrupt status, but it is still recommended to use external interrupt by connecting to a MCU;

After CC1101 restores IDLE mode or configured as sleep mode, it is recommended to reinitialize the power



configuration table.
