Gpy readiness

@kevin
NB-IoT will be later next month. We're trying to have a test firmware to support all 12 bands as well, but due to lack of certification and calibration procedures that will be for testing only. -
@jmarcelino I tried your method using my expansion board. I know CTS/RTS is working because it's handshaking correctly. When I take my FiPy off of reset, I can see the AT commands coming from the ESP32. However, it's not responding to anything I type into the terminal. Any thoughts on what could be happening here? Thanks!!

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