I have a problem - I cannot send data, when I set the request bit at positive edge there is no reaction from the module - even the LED TX. When I read the status of the communication block it says 0E42 and I cannot quite get what I am doing wrong. I would be grateful if somebody can help me. Best Regards, Svetoslav Veselinov
