Turns out the effect I was seeing had to do with the Terminal Emulator I was using, in this case CoolTerm. When I transferred to Putty, I no longer saw the delay in communication.

OK, I see the grid are soft buttons for sending different strings. Interestingly, I see that this app has the exact same behavior as Serial Terminal Bluetooth. That is to say that when the first send string occurs, nothing appears on the Terminal Emulator. Send needs to be hit again to see the string sent. But this is an offset, because when I press a different button with different string, the first string appears. It's as if during the first transmit, the data goes into a buffer but is not transmitted until the second button press. Note that this does not happen in reverse. If I type in the Terminal window, the string automatically appears on the phone.

I do have a question about dongle programming. I want to test the uart central function and how it interacts with the uart peripheral function. Can I use this thread or do I need to create a new ticket.

Hi Jim

The nRF Toolbox app can be used for UART indeed, or alternatively the nRFConnect app. Please check out these links (this and this) for an explanation for information on how to use the nRF Toolbox app.

Best regards,

Simon
