No delay of data output

5.7.1 Output delay

If the output delay is turned on, after receiving the air data, the module first pulls down the DATA pin, and outputs the

data through the UART after 10ms. It should be noted:

 After the output delay is enabled, streaming is not supported. The maximum data size of each packet is 244 bytes;

 After the output delay is turned on, if the air data packet is received too fast, the entire data packet will be lost.

The output delay is usually applied to the user MCU sleep situation. After the module receives the air packet, it wakes up

the user MCU through the DATA pin. After the user MCU stabilizes, it outputs data through UART.
