Rfid Readers perform switches between antennas while using multiple antennas. Reader runs one antenna while others sleeping and switches one by one. It makes it fast so running one antenna at a time doesn't matter. According to my observations, the time for every switch is 1 second. (After sometime I realised this 1 second is only for Motorola FX7500. Most other readers do it the right way, light fast like in miliseconds)
That is what I know so far.
Now, in my specific application I need this procedure to run faster, like 200ms instead of 1s.
Is this value changeable? If so, which message and parameter in LLRP can modify this value?
Actually the 1 second problem is with MotorolaFX7500 reader. By examining LLRP messages that Motorola's own library generates between FC7500, I discovered there are vendor specific parameters that can be used via custom extensions fields of LLRP. These params and settings can be found in Motorola Readers' software guide. This switch time is one of these vendor specific parameters, it's not a parameter of generic LLRP. A piece of code generating LLRP message including the custom extension with the proper format, solved my issue.
