Question asked by amaini.rafik on Oct 7, 2016
Hello everybody,
before I start I would like to thank you and I apologize for my bad English.
good, I want to use a dongle 3G/GSM (USB) with STM32f407 (the card discovery), and I do not know or begins
1- I use USB OTG or HOST?
2- a simple usb cable will be enough or I need a OTG cable?
3- what type of USB worker one I should use? CDC?
4- there are examples for this kind of application? Where can I find them?
thank you
