Subject: serial_bt: increase scan duration for BT/BLE connections
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=a1b80f9d314d5a3227ffe48354fbef3ba3c943f6;p=libsigrok.git

serial_bt: increase scan duration for BT/BLE connections

Some devices are slow to respond to scans. Increase the scan duration
from 2s to 3s. Tested with RDTech UM25C. Should be acceptable when a
manual scan takes some 6 seconds (BT and BLE) instead of 4.
