HC-05: transmitting data w/o newline


I am trying to interface an EM-18 RFID reader with an HC-05 for transmitting the detected RFID card serial number over BT. However, the problem is that the EM-18 does not send a newline character at the end of the RFID card serial number. The HC-05 seems to require a newline character to trigger transmission over BT [HC-05 is slave in serial profile]. Any thoughts on how I could get around this frustratingly simple problem - w/o adding another uC to simply add the newline character!

Thanks, NK2020
