and process it as per the Accept or Reject response from the user.

Version:0107 – Recreated images for Ver_0107 – 20

June 2018

Version:0108 – 29

June 2018

1. Version _0108 released for LM961/LM074 and LM068.

successful pairing. The RFCOMM-Serial-Over-Bluetooth ports were not being

created, and the error “device not supporting Serial service” was displayed on

Example-code.

of BD-address.
