Electron modem debugging

Troubleshooting
1

I am trying to get the AT commands sent to the modem dispayed on my serial monitor. I tried:
SerialLogHandler logHandler(LOG_LEVEL_ALL);
but I don’t see any AT commands. Has anybody an idea how to show the used AT commands? I am using v0.8.0rc12

Do you get all the other output?
How are you using the logHandler?
Did it work with rc.11?

Yes i see output like that:

0000002396 [system] INFO: Sim Ready
0000002438 [system] INFO: ARM_WLAN_WD 1
[ Modem::register ] = = = = = = = = = = = = = =

0000002774 [system] INFO: ARM_WLAN_WD 2
0000002774 [system] INFO: CLR_WLAN_WD 1, DHCP success

But some time ago I was also able to get output like this:

0000002396 [system] INFO: Sim Ready
0000002438 [system] INFO: ARM_WLAN_WD 1

Sadly I don’t remember which version it was (and also I am not sure how i achieved it).
I am just defining the variable as global variable at the top of my sketch:

SerialLogHandler logHandler(LOG_LEVEL_ALL);

and in my setup() I init the serial interface:

Serial.begin(115200);

@lympik I’m having this problem as well. Did you manage to solve it?

Yes if you are using the Particle Workbench you have to use “Flash application for debug (local)” which will flash a device os with logging enabled as far as we can tell.
