HI @hyhw_4628441 

The difference in operation can be specific to the laptop BT stack which is used. 

We will go through the logs in detail and update you. 

Meanwhile , can you please test this behavior with latest BTSDK app (in Modus Tool Box IDE) on 20706 ?  WICED 6.2 is too old. 

Regards,

Anjana
