 		 #164444 - And an IP Stack?
Responding to: ???'s previous message
Joe Gold said:
[...] but a microcontroller with USB host is more costly [...]

Joe Gold said:
[...] no to mention the development time to learn a new more complex 32bit processor core.

Joe Gold said:
And often you have to purchase the USB Host stack - which is many thousands of dollars


HSDPA is a packet protocol - so you'd also need an IP stack if you wanted to use that part of it.

But presumably not for just SMS?
