Applications:
1. Wireless telemetry charging for parking, parking lot;
2. Wireless modem Automobile inspection and four-wheel orientation;
3. Wireless sensor Industrial wireless remote control and air conditioning remote controller;
4. Observation and predication of oil well and hydrological information;
5. Point to multi-point wireless network, wireless on-the-spot bus and automatic data collection system
Description:
JZX873 the use of transparent transmission, in order to ensure the reliability and stability of the
user's system, plus the transmission check-sum or CRC check-sum error detection mode, the error
data re-transmission. Transceiver module buffer of 512bytes, means that users can be in any state
512bytes of data transfer 1, when the speed is greater than the serial port is set to air rate, is
theoretically unlimited length can send information packets, but does not recommend users to send
long data packets, the proposed length of each packet data between 60 ~ 100B, generally not longer
than the 120B, and recommended user program using the ARQ mode, the error data packets
re-transmission.
Trouble and solve ways:
Troubles: Between devices not communicated
Cause and Remedy:
1. Communication at both ends of the air rate, parity inconsistency
2. Frequency inconsistency
3. Without power
4. Module has destroyed
5. The pin of sleep mode not set
