I read r305 datasheet then follow the instructions. i am done initial step.. --> send hex values (refer datasheet) EF01FFFFFFFF010003010005 --> scanner also acknowledgemen EF01FFFFFFFF07000302000C My first problem was how to read hex values and how to check corresponding bis value in UART. Please help me.. last one week i am doing this but not solution find it.
