Data transmission

When the module is transmitting data, the host can send and receive data through the serial port.
To ensure transmiss data stably and smoothly,please note the following points:
  • Wireless transmission Match
To make the module communicate normally in Ethernet,band,channel and NET ID need to be set up all the same.The module has a 4-byte network ID can be configured.The modules with different network ID can't communicate each other.When the network ID is set to 0,it receives data information of module with any NET ID 
  • Data delay in wireless communication
Since the wireless communication transmitting device receives a certain amount of data from the terminal device,or need to wait a certain time no new data before starting transmitting,there is a delay from wireless communication transmitter to wireless communication receiver. In addition,it also needs some time from wireless communication receiver to the terminal devices.But the delay time is the same in same conditions(the time is decided by serial port rate and air rate)
  • Data traffic
There is 200 bytes buffer in the internal of the module.Data can be transmitted smooth when the serial port rate less than or equal to the wireless transmission rate.If the serial port rate is more than wireless transmission rate,it may occur data overflow and data loss .To avoid data loss or errirs,please set the serial port rate less than or equal to the wireless transmission rate.
  • Dormancy
Set pin CS to low,the module is in dormant state.The module can't be set its parameters at this time,nor data transmission.The power consumption of module is less than 5mA in dormant state.
  • Pin definition
Pin No. Pin Definition Description
1 TXD Serial communication data transmission
2 RXD Serial communication data receive
3 GND Ground
4 A+ Serial communication data transmission(485 level)
5 B- Serial communication data receive(485 level)
6 SET Configuration parameter enable(low level enable parameter configuration,high level output by default)
7 CS Module enable(low level dormancy,high level output by default)
