Since one week using the mangoh green with legato 16.07, I didn’t have any problems, but today I was trying to work with the UART so I made a basic program who just do an echo of the UART read.
So first I installed my program and then I set my UART 1 to the IOT 0 breakout board by doing this AT command in
Now in my program I opened the UART tty by using
open("/dev/ttyHSL1") and it was not working. Then I tested both UART using
microcom and a scope on the
IOT board connected to the
IOT1 and I deducted that the good tty was
So, knowing this I wanted to change my code, and It doesn’t work… I tried to uninstalled it with Dev Studio and by command line but both stay stuck in those state :
DEV STUDIO: Payload copied: 11734/11734
CONSOLE: Removing app 'echoUART'... ^C***Error: Couldn't remove app 'echoUART'
Also there is something very weird, after I tried to remove the app and it doesn’t success, the system began to be very slow. E.g: When I’m doing a
app status, there is 1s second between each lines.
Do you have any idea where I can find the logs for the command app ?
Hope you can help me understand the problem.
