The default connection is that sim #2 is connected to primary CF3’s uim2. But now I need to connect sim #2 to secondary CF3 because only the chip on this slot supports the RAT of my sim. How can I do this?
I read in the DV4 that it can be done by wither API command and hardware modification. I know the hardware method has to be done by un-soldering and soldering the tiny resistor. Thus the API command way is more suitable for me. But how can I access the pins on the GPIO expander when I code? I need to access the GPIO expander because the UIM signal is located at expander 2’s I/O_6 and 7.
You need to control U906_I07
You will need to use gpioExpanderServiceGreen to do so.
An example of using this service is herehttps://github.com/mangOH/mangOH/tree/master/samples/tutorials/mangOH_Green/gpio/TimerLed
Your binding would be:
yourApp.yourAppComponent.mangoh_simGpio -> gpioExpanderServiceGreen.mangoh_gpioExp2Pin7
Thank you very much. I used the binding syntax that you mentioned, but when I run my app (a very simple one seeing whether the pin is output or not), it shows that the binding is missing as shown below:
Besides, I also noticed that when the interface instance name that I specified in .adef is too long, after the app is started, a log message shows as follows:
Jan 6 00:56:04 | UNKNOWN[8235]/framework T=main | LE_FILENAME le_ref_CreateMap() 149 | Map name ‘refmangoh_simGPIO_ClientHandlers’ truncated to ‘refmangoh_simGPIO_ClientHandler’.
Is it normal? Do I need additional care on this issue?
