You Reply: To be more precise: It is a digital caliper , behaving like a BT HID keyboard. So, when the data button is pressed, the caliper sends a string of keypresses like "123.45\n". I want it to talk to an old machine, still working under MS-DOS and incapable for Bluetooth.
The task for the Bluno is to act as a HID host, connect to the caliper, receive the string and forward it to the machine vie RS232.
The question in short: Can a BT keyboard be used for inputs to the Bluno?
