Similar Lora Module Network Serial Port Long Distance CC1310 Wireless Module
VT-SA02D-433/868/915MHz Module is base on the SoC chip CC1310 of Texas Instruments design. It integrated with a high performance RF core, an ARM®Cortex®-M3 controller and a high performance amplifier.
It operates at 433/868/915MHz, max output power up to 23dBm.
Thanks to its ultra low power feature, the module is extremely suitable for the battery power systems. And thanks to its small size, the module can be easily installed in existing systems without any external circuits.

Troubles and Processing Methods
Troubles
Processing Methods
Short distance
1. Check the input voltage; ensure it is not lower than 4.5VDC.
2. Configure the output power parameter to the max.
3. Check the antenna; ensure it is not to be shielded.
4. Configure the radio data rate to a lower value.
Communicating failed
1. Check the input voltage.
2. Reconnect the module to the host.
3. Addresses of the communicating modules are all right.
High error rate
1. Antenna does not match to the module.
2. Co-Channel interference, try another channel.

FAQ
Description
Reason and Solution
Can’t communication
1.The power supply connect not well, check the module VCC whether it is out of maximum rating.
2.The signal line connect not well, check the module SPI interface.
3.The settings of the transmitter module and receiver module are not the same. Check these modules’ register configuration.
4.Signal block. If the transmitter work with a high TX power, and the receiver was put at a short distance(<0.5m), maybe there is a signal block to make no communication.
Communication distance is too short
1.The application environment is too bad or the antenna is shield. Put the antenna to a better place outside or higher throw a coaxial line , replace it with a higher gain antenna.
2.The work space contains a same frequency interference source, or a strong magnetic field interference,power source disturbance. Try to change the carrier frequency or get far away from the source of the disturbance.
3.The power supply is not strong. Check the voltage and the current whether it is enough.
High data error
1.The power supply ripple is too big, Change the power supply.
2.Check the module register configuration, it is recommended to set as the CC1120-datasheet.
3.There is a carrier frequency interference, change the channel.
4.The antenna unmatched to the module RF interface, change another matched antenna.
