RFID tag detection failure on Logout and Login to MI Client

92 Views

Hi,

We have implemented RFID in our MAM3.0 ; application. Every thing is working fine after login to client and could read the data from the tag. But once logout from the client (by clicking on logout from MI client) and login again, I am unable to read the data from the RFID tag. Seems that it is not connecting to the RFID reader. I am getting CAF exception and RFID read exception.

I am using MI2.5 SP 21 Client

Below is the trace of the exception

RFID READ ERROR: RFID tag detection failure

[20090205 15:06:07:058] E [Unknown ] com.sap.mbs.mam.rfid.exception.RFIDTagAccessException: RFID tag detection failure

After restarting the device, I am able to read the data from RFID tag. Did anyone encounter this kind of error for this particular scenario. Please advise how to resolve this issue.

Thanks in Advance,

Chinna.
