N
If the radio rate is equal to the serial baudrate, the radio packet is longer
than the serial frame, due to radio protocol overhead. If the current radio
rate is 10 kbit/s (Narrow band), a serial baudrate of 4800 bauds can be used
without flow control, while using a serial baudrate greater or equal to 9600
bauds will produce data overrun.
We recommend to use RTS handshake (S216=0) for serial baudrate
greater or equal to the radio rate in order to avoid FIFO buffer
overlap.
For example with serial baudrate greater or equal to 9600 bauds for
Narrow band (radio rate 10 kbits/s) and serial baudrate equal to
57600 bauds for Wide band (radio rate 57600 kbits/s).
N
when changing the serial link configuration (rate, parity, stop bit…), the
answer is done using the old serial link format, the next command must be
sent using the new serial format.
For avoiding character lost, you should:
- use the flow control (S216=0),
- or use a serial rate lower to the radio rate,
- or limit the size of serial data to one radio packet.
