devlist — List of nearby Bluetooth devices
List of nearby Bluetooth devices, returned as a table. The table has the following columns.
Name — Device name
Device name, returned as a string scalar. Multiple devices can share the same name.
Address — Device identifier
Device identifier, returned as a string scalar.
Channel — Device channel
Device SPP channel, returned as a categorical scalar. If the channel is
unknown, the value in this column is
Status — Device connection status
"Ready to connect" |
"Requires pairing" |
Device connection status, returned as a string. You can connect to a
Bluetooth device using
bluetooth only if
its status is
"Ready to connect". Possible values
|Device supports SPP, is paired, and not connected anywhere.|
|Device supports SPP and is not paired.|
|Device supports SPP and is connected.|
|Device does not support SPP.|
|Unknown if device supports SPP. Device is turned off or fails to respond to scanning request.|
