In order to prevent loss of characters, you should:
• useowcontrol(addressedmodewithhardwarehandshake).
• or use a serial transmission rate less than or equal to the radio transmission rate.
• or limit the size of the serial data to the maximum size of the internal buffer (S218).
NOTE 3
(S200 register) cf page 10.
NOTE 4
The preamble length is linked to the current radio transmission rate.
Preamble values are:
The default preamble length The minimum preamble length
wide band channel
(high radio transmission rate)
5 ms 4 ms
narrow band channel
(low radio transmission rate)
20 ms 10 ms
PLEASE NOTE
It should be borne in mind that reducing the default preamble length will reduce the transmission delay but risks
generating possible errors in the frame transmission rate (up to 1 or 2/1000)!
In the case of narrow band, it is not possible to set the preamble length below 10ms.
NOTE 5
Whenyouchangetheseriallinkconguration(transmissionrate,parity,stopbit…),theresponseismadewith
the previous format of the serial link. It is the next command that will be sent using the new format of the serial
link.
NOTE 6
When the serialization of the RSSI is selected (at receiver), a warning (WARNING_3) appears, asking the user to
ensurethatthesideofthetransmitter,theowattheselectedserialisequaltotheselectedradio.
In the opposite case, a phenomenon of fragmentation of data may appear, making it completely unusable data
received on the serial link.
