i too have been experimenting with the RS232 node and Bluetooth. i have a small app sending data from my pocket pc over bluetooth to the bluetooth serial port (COM4) in my laptop. as with some others’ rs232 setups, it works great when sending and receiving from HyperTerminal. and monitoring the traffic on COM4 with a port monitor shows nice little bursts of activity when a i send or receive some data from the PocketPC to HyperTerminal.
But, when i connect with the RS232 node, using the same settings, i can SEND data out pretty well, but it seems i can only RECEIVE data when i send it in large blocks. Also, the Port Monitor switches into overdrive and it seems vvvv is sending a READ command to COM4 once every MainLoop frame. it almost seems as if this is keeping the port so busy, it can’t grab the data unless its timed just right - but perhaps its just a coincidence? i have to constantly press ‘send’ on my PocketPC app and every once in a while, data will come thru.
is there some kind of buffer that fills up before it dumps into vvvv? is there any way to have 4v READ from COM4 only when data comes thru- as it does in HyperTerminal? i tried different Baud rates and MainLoop rates and neither seemed to make any difference.
i searched through all the other rs232 threads and found bits and pieces, but no one seemed to have this particular issue. any thoughts?
