[quote user="lelisele"]The solution could be: each time when application receive one character make echo and sent it back. [/quote]

Yes, you could send it back to the terminal with app_usbd_cdc_acm_write().

Alternatively, just enable local echo in Putty:

Thanks for your answer, Currently the sequence is: I hit message on the ptty via USB Virtual COM without any echo to verify what shall be sent and the message is "visible" only after CR and ONLY on the Android. That is common using for terminal. On the Android it is OK.We can observe our message before sending. The solution could be: each time when application receive one character make echo and sent it back.

Hi,

Could explain this some more? When you send data from the PC terminal, to the nRF52840, you want the nRF52840 to echo back the data it received?
