4.3 Program burn

The module is a SoC module with its own GPIO port. Program download uses the CC series dedicated downloader:
JTAG downloader (or TI's official CC1312 supporting development board). Serial ports or any other ISP or ICP
tools cannot be used.
The figure below is a schematic diagram of the JTAG connection (XDS100). For the specific development method,
please refer to the relevant Ti official documents (the TDI and TDO pins may not be connected).

5 FAQ

5.1 Communication range is too short

The communication distance will be affected when obstacle exists;

Data lose rate will be affected by temperature, humidity and co-channel interference;

The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground;

Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea;

The signal will be affected when the antenna is near metal object or put in a metal case;

Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the

distance);
The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the

transmitting power;
Due to antenna quality or poor matching between antenna and module.


5.2 Module is easy to damage

Please check the power supply source, ensure it is in right range, or the module will be damaged;

Please check the stability of power source, the voltage cannot fluctuate too much;

Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic

susceptibility;
Please ensure the humidity is within limited range, some parts are sensitive to humidity;
