z ACK/NAK
The reader sends data between the host by using the following procedure.
1 Read data is sent to the host from BL-N70RE/RKE.
BL-N70RE/RKE waits for a response from the host. During this time, a new barcode
cannot be scanned.
2 The response is sent from the host to BL-N70RE/RKE.
• If ACK [06h] is received, data transmission has completed successfully, and the BL-
N70 is ready to scan a new barcode.
• If NAK [15h] is received, the BL-N70 resends the same data and waits for ACK [06h].
