PIC-GSM Board

This is not the correct forum I’m afarid but there’s no GSM area here. since its wireless I figure here is as good a place as any.

I bought two PIC-GSM development boards a few days ago. Thank you for the prompt shipment.

I have been able to make a call and send an SMS with the Embedded web server although its very erratic and locks up after most every call. But it does work. I do understand its just Demo software so its not that big of deal.

The major problem is I can not talk to it via ‘AT’ commands. I’ve tried two different terminal programs. I can connect to the FTDI 232RL chip so I don’t think its a driver problem. I’m using 115200 baud, 8-N-1(default). I’ve tried all the handshaking protocols. The manual says RTS/CTS is default. Am I missing something here?

All the Jumpers are in the default settings although is a bit confusing in the documentation. I’d like to test it using ‘AT’ commands via a terminal program then write the PIC code to do the same. At this point I don’t care about the web server part (I’ll use it later I’m sure).

Whats the trick to be able to send ‘AT’ commands to it? I’m sure something is setup incorrectly but it looks like it should work “as is” as per the manual and as shipped.

There a couple other problems / questions I have.

  1. Witch ICSP connector description is correct? The one in the manual or the one on Olimex’s web site. I’m using a ICD2 and not a clone one

  2. The supplied demo source software will not load into MPLAB. MPLAB says its corrupted. I’m using ver 8.14 of MPLAB. I tried downloading it again from Olimex with the same results.

Thank you for any help you can provide. It looks like a great board and it will be lots of fun once I can get past the first few issues.

Thank you

It seems the problem is related to windows Vista. Using the same terminal app and settings on XP and The ‘AT’ commands works fine.

Presumably you’re on a different computer when you use XP? It may well be because of differences in the serial ports you’re using.
