[quote user="pail"]so.. you're saying start with example"ble_app_uart" and copy and paste the main code of example"ble_app_beacon", aren'tyou?[/quote]

For instance yes, you can then compare with the original main.c from ble_app_uart on how to setup UART. By using ble_app_uart as starting project then all the include files and sdk_config is setup correct.

[quote user="pail"]So does it mean that I set up an external pull-up resistor(typ. 13k ohm)?[/quote]

For instance yes, this is just to ensure that the RX pin is not floating, because this will cause UART framing errors. The pull-up can be 100kohm or bigger (it can be 13kohm also, but no need to be this low).

hi Kenneth

thank you for your reply.

so.. you're saying start with example"ble_app_uart" and copy and paste the main code of example"ble_app_beacon", aren'tyou?

however, I'm not sure your Tip.

You said Tip: Make sure that the RXD pin is pulled high (for instance with pull-up, and not floating).

So does it mean that I set up an external pull-up resistor(typ. 13k ohm)?

or you want me set up a pull-up internally?

Hello,

My suggestion is to start with the ble example with uart support:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/ble_sdk_app_nus_eval.html

It should be possible to modify the advertisment to contain beacon data, and then you already have uart working.

Tip: Make sure that the RXD pin is pulled high (for instance with pull-up, and not floating).
