Arguments to NRF_LOG_DEBUG() sometimes missing in RTT output, SDK 15.3.0.

[Eliot Stock]

I recently migrated from SDK 14.2.0 to SDK 15.3.0 and just noticed that some but not all of my logging is broken. A logging macro call such as this:

NRF_LOG_DEBUG("Output power: %s dBm", (int)m_modem.response);

will log only:

D modem Output power:  dBm

when I expect to see:

D modem Output power: 14 dBm

Is this a known issue? Is there a workaround?

Hmm I believe you should use '%d' for decimal integers. Right now it's expecting a string, but you've provided an int. 

Are you sure m_modem.response has a value when you call the NRF_LOG_DEBUG function?

[Eliot Stock]

That value is in fact a string. In previous SDK releases, the cast to (int) was required to prevent a compile warning or error. Is that no longer the case? It seems not. So I now need to go through all my logging and remove them, and it'll work again?

[Eliot Stock]

Any update here? Should I create a private case and add the whole codebase?

[haakonsh]

We're a bit short staffed during the summer vacations, but I'll try to get hold of someone that has worked on the logger module.

[Eliot Stock]

OK cool, thanks.

[Eliot Stock]

Any update on this please? It's been a while.

haakonsh, how can I make some progress here please? Would a private case with the whole codebase help?
