Redpark Serial Cable not receiving data

Question

I have a C2-DB9 serial cable from Redpark for use with an iOS application that seems to be not working as required. I have a device that connects to the RSC cable and also to a PC via USB for power only.

I have utilised the Redpark SDK provided with the hardware and implemented the delegate methods accordingly:

- (void) cableConnected:(NSString *)protocol;

- (void) cableDisconnected;

- (void) portStatusChanged;

- (void) readBytesAvailable:(UInt32)length;

Now, all of the methods apart from readBytesAvailable behave according to specification. However, I have not received any communication back via this delegated method.

To check that the device is not faulty, I have installed some generic USB to Serial drivers and used ZTerm to confirm its operation - this gives me the returned data immediately.

I know I must be missing something but I am at a loss as to what it is.

are you setting baud rate and opening connection via RscMgr's setBaud and open methods on

(void) cableConnected:(NSString *)protocol;

I am indeed. I am now in fact receiving the data but I am having trouble reading from the UInt8 buffer. – JordanMazurke Apr 04 '12 at 12:23
`cableConnected:(NSString *)protocol` doesn't seem to be called for me when I plug the cable in. What should I do...? – fatuhoku Jun 03 '13 at 11:46
I'm in the same situation as you, my readBytesAvailable is never called. What did you do ? – Macaret Jan 04 '16 at 11:44
