We are working with ST25RU3993 eval board and controlling it from linux based STUHFL C code base.
Could you please suggest best config for reading weakest tags with ST25RU3993 using C code base.
Hello,
Reading "weak" tags depends on different factors. Its not possible to have one configuration setup for all possible application/HW setups. The following list gives an overview of the most important factors that may influence the read performance.
- Tag population
- Distance between antenna and tag
- Location of tag in field
- Field propagation
- Used frequency
- Used Antenna.
- Tuning state
- Noise or crosstalk
- ..
In general to have the best possible reading performance the following settings should be optimized for the given HW setup
- Before scan run exact tuning and during scan use automatic retuning
- Mute found tags by using sessions and targets or Select commands.
- Try optimized antennas for the setup
- If possible move tags
- Use different frequencies, that are allowed in the region
- Try to increase output power and sensitivity
- Use adaptive Q adjustment for faster anti-collision
