[quote user="penguinwashere"]Thanks for your response. [/quote]

No problem at all, I am happy to help! :)

I am glad to hear that the examples are working as expected now, great!

Please do not hesitate to open another ticket if you should encounter any other issues or questions in the future.

Good luck with your development!

Best regards,
Karl

Hello,

I want to first verify my understanding of this example. In this example, should I be able to type in my terminal to send characters back and forth over bluetooth? This is my understanding of this example:

Device 1 <--> UART <--> Bluetooth <--> UART <--> Device 2

Your understanding of the example is correct, so long as you have one device programmed with the ble_app_uart_c(entral application) and one with the ble_app_uart (peripheral application).
The central will look for devices that advertise the Nordic_UART name, before initiating a connection.

I cannot talk from my central device to my peripheral device though. whenever I try this, I get the following errors from RTT:

Which serial terminal are you using on your central side / how are you inputting the UART data to the central device?

app: Connecting to target 3E0D9D17F3CC

app: ATT MTU exchange completed.

app: Ble NUS max data length set to 0xF4(244)

app: Discovery complete.

app: Connected to device with Nordic UART Service.

After the last messages in the log, where the discovery successfully completes, are you then able to send from your central device to your peripheral device?

What does your peripheral's log look like when you are doing this?

Best regards,
Karl

Thanks for your response. I eventually did get this example to run correctly after realizing the central to peripheral thing. The errors I received after that were for an example I found on github for time syncing.
