Hello,
i noticed that even i send AT%XMODEMTRACE=0 with response "OK" the bsd lib triggers EGU0 / Trace interrupts. The modem is not started, but the bsd lib got succesfully initialized.
I would exspect this IRQ not beeing fired in this case after using the AT command to turn them off.
See attached a uart log of this situation in a test scenario just going to sleep (WFI) and wakeup with a 5 second interval. The "problem" is in this case that the bsd trace IRQ wakes up the CPU rahter than the RTC compare interrupt as exspected.
Thank you for an explanation.
BR
Theo
