RE: SDK17.0.2 code wierd thing, code doesn't execute

Hello,

[quote user=""]See the info below, I put a log just before it, you can see from the RTT viewer that it executed, but the following log "Adding item to the queue...." doesn't show up.[/quote]

Are you only using the deferred logging option? Have you changed your default logger severity level, since you are using DEBUG level severity for your statements? Are you using a nRF52 Developement Kit, or a custom board?

[quote user=""]I tried many times, almost crazy, the new SDK use a QUEUE thing that make the code a bit complicate. Is there any benefit for this?[/quote]

The GATT queue is used to buffer GATT requests to the SoftDevice, so it may process them at a more opportune time.
This is very useful when frequent requests are made to the SoftDevice.

Best regards,
Karl

Notice the dual "<debug>" in the next line? The debug message was lost due to buffer full.

The queue allows for printing messages in timing sensitive code. I recommend either printing fewer messages or increasing the log buffer size.
