#5_"The box, the box!"

I have to apologize that this project has came to such a sad state of stalling.

I have continued to research and see if there are other ways that I can get this working but so far no luck.

I have completely ripped the project back down, retested the gps with arduino Uno and then re-assembled and retried code provided as good to go for serial/gps testing.

Code is same as in Blog 8.

I did find some hints that others have had the same issue: https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/586961/2165670

"Please help somehow the serial monitor is not displaying any readings when I connect the GPS to P3.2 and P3.3 ..."

and

"Well I have been working in arduino for sometime now and the first part was implemented correctly..No problem at all...But when I am going to implement the same in msp432 nothing is happening..."

This sounds mighty similar to what I am running into.

Later he references success from information he found at 43oh.com but never details what was done. :-(

"Thanks at least I can now get the location in my serial monitor...Forum 43oh was of great help"

and

"Thanks for all your help...I was finally able to successfully complete the whole project"

No links, so I have been checking the forum myself but keep getting:

Sigh...

One of the items I referred to quite a bit when planning this was dougw awesome table of pins from his blog 5 when he was explaining his pcb. Safe and Sound - Hazardous Gasses PCB - blog 5

I really found it helpful!

I can't remember off the top of my head but I was able to get it to work with direct as well as soft when I first started playing with the project. Something had to be done but it did work. :-)

Here's the pinout for the MSP432 board. You should have that already as it comes with the board, but it might be useful to others who don't.

Did you swap the connections between the two boards? [Connecting TX to RX.]

On the Adafruit board, the TX and RX labels are from the point of view of the GPS module.

I don't understand how the 'direct' connection can actually work when it's used with an Arduino, since they seem to have the two TXs trying to drive each other. Does everyone use the 'soft' connection on '7' and '8', perhaps?

I hadn't actually registered and asked a question yet. That will be what I next do. Honestly I am not used to a forum that requires you to be a registered user to not have it plainly state it as such. Their error I shared hinted more to a site problem. And I am able to browse the higher levels of the forum. Lesson learned!

Hi John,

It seems like the issue with not being able to get to that forum section is probably that you aren't a registered user? I just registered and now I can get to that section fine.

Best Regards,

Rachael
