Well, to tell the truth, I just got started with the Xbee and haven't connected them to the microcontroller yet. From what i understand from the data sheet, you check CTS to ensure that you aren't filling the data input buffer and if it is high, then you should stop sending and wait till it goes low to send data to the Xbee again. I will be sending data from the micro to the Xbee intermittently, maybe a 100 bytes at intervals of 10 seconds - this is just an estimate - so i might not need the cts control, though if you guys think its good practice, it might be advisable to do it.
I had a question about connecting the UARTs of the Xbee and the micro: i am using a dsPIC30F3012 which operates at a voltage range of 2.5 to 5.5 V while the Xbee is 3.3V; do i need a voltage level translating chip in between the Xbee and the micro when i connect them? I have seen yes and no answers on the web so far, and was hoping for something definite. the micro will probably be running at 5V; though if i ran it at 3.3V, then i assume i wouldn't need a translating chip?
I would greatly appreciate it if you could clear this up for me.
