NRF RTT Logging get buffered fragments

[scottc19]

I am using NRF5340 with NRF connect  (Zephyr) and  logging out to RTT (printk or printf, etc) , which works but sometimes I get buffered fragments and dont see the rest of the print until more events happen that forces it to flush.  Is it possible to force a flush and ideally not hang the system if RTT is not connected?

I strongly recommend looking into the source code here. RTT logging has a mountain of config options and its easier to see what these do in the code itself.

I'd try configuring a bigger log buffer first, the 5340 usually has unused RAM left.
