Hi!
I need to connect a MCU to a mobile phone. The MCU is going to collect data and when connected to a mobile phone, the phone shall then send this data to a webb-server.
However, my concern is the connection between the Mobile phone and the MCU. USB or bluetooth would be prefered. Do i need a USB-host in the MCU if I choose USB? And if bluettoh, can i use a simple serial-port connection?
Does anyone have any experience?
Best regards, C
