change log level of application not work

[SBKK]

i am using dlt-control to change some app log level

i have a app registed as "P1" with 1 context and a app registered as "S1" with 3 context

i want S1's 3 context to switch to log_level 2

dlt-control -a S1 -l 2 localhost this not work : apid : P1 ctid: xxx0 apid : S1 ctid: xxx1 apid : S1 ctid: xxx2 apid : S1 ctid: xxx3

if i change "S1" to "O1", this work : dlt-control -a O1 -l 2 localhost apid : O1 ctid: xxx1 apid : O1 ctid: xxx2 apid : O1 ctid: xxx3 apid : P1 ctid: xxx0

in the code src/daemon/dlt_daemon_client.c: dlt_daemon_find_multiple_context_and_send_log_level

looks like with app_flag == 1, if not match, it just break ? since the contexts are sorted，so S > P not work, and O < P work

Can you please enable log of dlt-daemon, reproduce and share with me (dlt.log file)? How to enable dlt-daemon log (via dlt.conf file)

• LoggingMode =2
• LoggingLevel = 7
• LoggingFilename = /tmp/dlt.log

Thank you, Thanh
