Hi Mahesh

Due to some sickness internally and a bank holiday in Norway on Wednesday May 1st, we will need to get back to you on Thursday for some proper feedback on this case. Thank you for your patience. In the meantime, can you share some details on what exactly this "simple app" is doing and what drivers/libraries it is using?

Best regards,

Simon
