Issue with UART on nRF52840DK multi-link-multi-role example

[girts]

Hello,

I`m trying to get this (https://github.com/NordicPlayground/nrf52-ble-multi-link-multi-role/) working properly to test the possible working range between two nRF52840. I have flashed demo ble_perephial_long_range_color.hex on one of my nRFs, and aggregator on the other. When I connect to the aggregator from my phone, i see rssi of the perephial there and everything is ok, but i would like not to use my phone and view all the information via UART USB. I have connected the aggregator to my PC and when opening the serial console, ugly characters are displayed. BLE Interactive Command Line Interface Example worked just fine, I was able to open the serial communication with the same settings on my PC and everything worked. What could possibly be the problem?

Hi

By default the UART baud rate is set to 460800 baud, so unless you set this in your terminal the characters will appear incorrectly. 

I did this to ensure that the UART wouldn't be a bottle neck when connecting multiple devices to the aggregator. 

Either change the baud rate in your terminal, or change line 1405 of main.c to have the aggregator use a different baud rate. 

Best regards
Torbjørn

Thanks! I thought hat the Baud rate should be the same as in other examples. Thank you! It works with 460800.

Good to hear that you got it working 

This could probably have been better described in the documentation ;)
