Q: 

I have to make an iPhone app that communicates with devices that support Modbus Protocol.

I have to be able to communicate wirelessly which means it would either be MODBUS TCP/IP over wifi or MODBUS RTU over bluetooth. I cannot find any modbus implementations with an objectiveC wrapper, but I can write the wrapper over a C library. How should I go forward?

+1  A: 

You won't be able to use the Bluetooth method: the iPhone can only talk to devices that use the iPhone Accessory Protocol over Bluetooth.

Wifi should work though. Using the C wrapper will also work: objective-C is a superset of C, so you should be able to use the library unmodified.
