Hello, thank you for your reply.The monitoring from the TEC is basically a good approach. The problem is that I want to stop the transmission after a few retransmissions (<= 10). Since there is no interrupt when the TEC is increased, I would have to ...

Hello STTwo-32Thanks for the quick reply. I'm a bit confused from the link you sent. I get .svd files with it, but I need the .bsd files.Best regards
