hi,iam working on a embedded system which has a gsm module and a wifi module as peripherals.The objective of the system is to create a hotspot so that wifi enabled devices can connect to the hotspot.can u please describe a brief workflow...thanks in advance

 

1) Choose a gsm module, choose a wifi module. It would be best to find such modules that someone has already used in some project. Learn how are those modules used in the projects.
2) Choose a CPU and/or suitable development board.
3) Write the code.
4) ???
5) Profit.
