5.4.5 Get-Bootloader-Revision (01-05)
This command returns the bootloader revision of the reader. The version number is split into blocks of 4 bit. One
of these blocks represents a decimal character. There are always two characters in front of the point and two after
the point. So the first two bytes of the bootloader revision are not used.
Field-Value: String with variable length
Example:
PC -> Reader: 52 46 45 01 0105 02 00 04 cs
Reader->PC: 52 46 45 01 0105 02 04 03 00020005 04 cs
dataLength = 0x04 -> 4 Bytes
bootloaderRev = 0x00 0x00 0x01 0x05
5.4.6 Get-Attenuation (02-01)
This command returns the maximal potential and the current attenuation in dBm.
Parameters: none
Return Values: RFE_RET_VALUE status, unsigned short maxAttenuation, unsigned short currentAttenuation
Example:
PC -> Reader 52 46 45 01 0201 02 00 04 cs
Reader->PC 52 46 45 01 0201 02 07 03 00 000F 000A 04 cs
dataLength = 0x07 -> 7 Bytes
status = SUCCESS
maxAttenuation = 0x000F -> 15 dBm
currentAttenuattion = 0x000A -> 10 dBm
