Gpy readiness

Hi @brotherdust

I think your TX and RX are swapped if you want to communicate with the modem.

Also explains why you see the ESP32 - in this case you want to emulate it so you should not see it.

Please try swapping th RX/TX and keep the ESP32 in reset.

There. are. no. words.

Thank you.

Is there anyway to get to the LTE TX & RTS pin on the GPy?
Are they available on the pads on bottom side of the PCB?
I'm really tired of recompiling each time I think I have some magic AT command to get the Sequans modem to play ball...

@redferne Aren't the pins documented? Looks like it to me. If I had a GPy, I would use my expansion board similar to how I did it with the FiPy; just with different pin locations. =)

Ah, I see now what you are saying. That's a bummer they didn't break it out on any pins. Looks like you'll have to play whack-a-mole for a bit to find those pads!

[Redferne]

Yeah. On the GPy there's a bunch of pogo pads underneath. I might just start testing them one by one... ;-]

[jmarcelino]

Sorry to say but those UART pins are not mapped onto test points or external pins on the GPy. They only connect to the ESP32.
