CONNECTION
LMX9820A acts as master for several slaves.
Example: Two sensors with LMX9820A; one hand-held
master device with LMX9820A.
Serial Devices #2 and #3 establish the link automatically as
soon as they are contacted by another device. No control-
ler interaction is necessary for setting up the Bluetooth link.
Both switch automatically into transparent mode. The host
sends raw data over the UART.
Serial Device #1 is acting as master for both devices. The
host controls which device is sending data, using the “Send
data” command. If the device receives data from the other
devices, it is packaged into an “Incoming data” event. The
event includes the device related port number.
If necessary, a link configuration can be stored as default in
the master Serial Device #1 to enable the automatic recon-
nect after reset, power-up, or by sending the “connect
default connection” command.
