1、When Module A transmits data and module B receives data
That is, the delay time that the terminal A (connected to the module A) sends data to the terminal B (connected to the B module) by wireless. Which be fixed to the time for transmitting 15 bytes. This time is related to the air baud rate, but not to the interface baud rate. details as follows:
Baud rate（Bps） | Delay time（ms） |
19200 | 8 |
9600 | 15 |
4800 | 30 |
2400 | 60 |
1200 | 120 |
That is, the time for converting from the receive state to the transmit state, or from the transmit state to the receive state. During this time (100us), the module cannot receive air data.
