  • FAQ for Ellisys
    • 1. How to judge the signal quality of air interface packets? How to improve the quality of captured packets?
    • 2. When I capture packets, I can only capture a small portion of the packet, and the packet capture device and software are running normally, but there are no more packets after that, what’s wrong?
    • 3. I can only catch classic broadcasts, but not extended broadcasts, what’s wrong?
    • 4. The program is running and I can see the broadcast packets on the packet grabber, but I can’t scan the device through the cell phone tool or the probability of connecting to the device is very low after I found the device, what’s the problem?
    • 5. How does a packet grabber pull signals from a program while grabbing empty packets?
    • 6. Why some encrypted packets can be decrypted while others cannot?
    • 7. What is the problem that the packet grabber is running very slow?
    • 8. After a long time of packet capturing, the packet capturing software is very laggy and fills up our system disk, what should I do?
    • 9. How to check the current broadcast period or connection period by empty packets, so as to check that our code is configured as expected?
    • 10. I want to make sure that my broadcast data is set up correctly, or I want to make sure that the connection data is sent out, where should I look at the sent out air port data?
