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. 




Hello Anjana, thank you for help.

Please share the update to me, after reviewing log.

I want to update the SDK, but its project is already in mass production. so i`m sorry to can`t update the SDK.

again, thank you for help always.
