Parallax GPS Module

BobW

Hello,

Please pardon my confusion between the BS2 and BS2sx modules.
I have a perfectly good GPS Module from Parallax that is fine on a BS2.
I've really run into a wall trying to see what's different on the BS2sx that is preventing it from running.

All I get on the BS2sx is "No response from receiver module."
FWIW, I was hoping to get the BS2sx to read the GPS module and then, using the Embedded Blue bluetooth module, communicate that data through my phone and to a web address.

Using a BS2 I don't think is out of the question, I am just trying to get an understanding of why it's not working, for this noob, on the BS2sx.

Thanks for any help!
Bob

Did you adjust for the difference in Baud speed settings?
·· BS2, BS2e, and BS2pe = INT(1,000,000 ÷ baud rate) - 20
·· BS2sx and BS2p = INT(2,500,000 ÷ baud rate) - 20
·· BS2px = INT(4,000,000 ÷ baud rate) - 20

If you are using 188 on the BS2, then you should be using 500 on the BS2sx when referring to baud speed in the SERIN or SEROUT commands.
Likewise if you are using 16572 on the BS2, then for the BS2sx you should be using 16884 when referring to baud speed in the·SERIN or SEROUT commands.

Thank you VERY MUCH!

That was it. Now on to getting the bluetooth adapter to contact my web server through my phone.

Truly appreciate the quick help!
