This may be unrelated but you might also want to try this.
Hey, first I want to apologize for the long delay. I believe there was a glitch in our system as it was down some over the holiday. I looked more at your issue and I noticed that the article you posted said:
"Yes, LabVIEW PDA Module 7.1 and later supports Bluetooth communication on Palm OS 5.0 or later devices and Pocket PC 2003 devices with the WIDCOMM Bluetooth driver version 1.4 or later."
I also noticed that you posted:
"LV7.0f1 with PDA for Palm OS and Palm OS SDK installed, BitVirtSerOpen.c added during building process."
Are you attempting this with LabVIEW 7.0? If so, this is not supported.
Also, the reason for the error is all PDA VIs are converted down to c before they are transfered to the PDA. Obvisuosly, one of these files is not being transfered. This may be because it is not supported.
Let me know!
Note: The VI is built to work with the LabVIEW PalmOS Module 7.0 and PalmOS v3.5 or later with Bluetooth installed. In addition make sure you have the "Palm OS 5 SDK (68K) R3" installed. The SDK contains Bluetooth APIs functions that are needed in order to compile the c file. The installer is available at the below link.
