I thought it was working...and it is to a point. However I am seeing an anomaly I can't understand. I hope you can help me figure this out.

I am programming my application with the below code using a PICKIT2. I have the PICKIT2 set to "VDD Target" so that the PICKIT2 is not providing power...my application has its own power.
The programming of the device is normal and it starts working and executes the program normally as long as the PICKIT2 is still connected (but not providing power).

However, when I disconnect the PICKIT2 and power down my application and then reapply the application's power, the code is obviously stopping execution at the point in the code where the AT+i coommand is given to set auto-baud at 9600 baud. I know this from the WRITE 4,4 statement not appearing in EEPROM after the test run and the LED_RED not blinking. However, when I then reconnect the PICKIT2 and load the PICKIT2 software with its screen, my application then works normally and executes the complete program with the LED_RED blinking as a heart beat during the BOOT loop.

It is almost like the iWiFi module isn't getting power when the PICKIT2 is disconnected and therefore the AT+iBDRA fails...but it is getting power...I checked with a voltmeter.
I am stumped and can't go any further in integrating this code with my overall application until I resolve this anomaly.

Do you or anyone have any ideas why the iWiFi module would act this way with this code and this scenario?? At least I was able to use this code when it worked while PICKIT2 was connected to identify the IP address, log into the iChip web server from my PC via the wireless route,r and set parameters on the iChip.
