1. recommended user program using the ARQ mode the error data packets retransmission As follows If the actual error rate 10 4 users need to send 1KB about 10000bit information if the 1KB data as a packet sent at least theoretically there will be a data error in the receiver then the 1KB data can never be received correctly If it is divided into 10 packages each package 100B then send 10 packets the packets according to a probability of only 1 error the error in the form of a packet retransmission by ARQ 1 although it took more than 1 packet and the efficiency decreased by about 10 but it can guarantee all the information is correctly received In the work on JZ861 There are two ways of working first for the conventional model which Module is powered On is in receive mode you also can be sending data The second is sleep mode that is through the power module in a dormant state to be awakened by the user s foot control module the module can send and receive data In the application of JZ861 module the module uses a wide voltage range but also be divided into two kinds of voltage the first for the 5V power supply module also known as conventional modules voltage DC 3 3 5 5V The second is 3V power supply modules custom module for the user the voltage of DC 2 7 3 3V users in the use of power to DC power supply the current must SHENZHEN J IZHUO TECHNOLOGY CO LTD TEL 0755 83304518 83308451 Tech 0755 61319411 61319410 WEB ht2.
