I have just posted the following on the Spark Fun Electronics Technical Forum... I am posting here as well in case one of you have seen this problem.

Hi,



I recently purchased a SMiRFv2 and am having problems getting into the configuration utility.



I am running Hyperterminal V5.1 under XP home SP2.



First of all, I get two New Hardware Found dialogs when I first connected the SMiRFv2 to my PC. The first was for the CP2101 and the second for the SFE RS232 controller. This does not concern me too much. I mention it because a double install dialog was not mentioned in the PDF documentation.



I have insured that HT and the SFE device driver are both configured for 9600, 8, N, 1 (I am on COM6).



The multiple control S command does not bring up the SFE configuration screen as described in the PDF data sheet. I have tried this with the remote SMiRF powered and unpowered.



I then ran some user code for the remote SMiRFv2 (I am connected to a PIC18C) and was initially unable to establish communications.



While I was looking at my user code, I noticed that communications had been established with the remote and I was getting data on HT.



About a half hour later, the communications halted and HT is, once more, dead. I have nor been able reestablish.



When I plug in the USB part of the SMiRFv2 pair, the status light is lit for about a minute and then goes out. When I run the remote, the remote status LED blinks once a second which is consistant with my PIC18C code (sends 30 to 50 ASCII data characters once per second).



I am mostly concerned about not being able to access the SMiRFv2 configuration via multiple control S keystrokes as per the data sheet.



Any ideas?

By the way... Thanks to Kevin for the printf utility code... For the half hour it worked, it worked really well!

I will post here if I get good feedback from the SFE site.
