Hello,
I have some trouble with T-Motion boards and I'm searching for possible reasons for malfuction. So I found in your Readme the wiring table for GPIO from STM32L073RZ to SX1276 and CXD5603GF. I would appreciate, if you could tell me the source for this information. Are you sure, that PB2 is driving the RST of the CXD5603GF? What is the sense of the S76G Pin 24 GPS_RST_X? From my understanding, this is the RST for CXD5603GF. Or is there an 'OR' function in front of CXD5603GF for signal GPS_RST_X and PB2 of STM32L073RZ?
Thank you for you support
Wolfgang

1. a typo in firmware folder name ?

   f-ri-mware:

2. confusing "T-Monitor" label

   there are several places in README where "T-Monitor" name is in use. What does it belong to ? Is it firmware name for T-Motion board ?

3. dfu.hex file is confusing as well.

   It supposed to be a firmware image of the sketch. However, in fact (according to 'hexview' and UNIX 'dmesg' output), it looks to me like an intermediate DFU bootloader for STM32:

[3936714.355437] usb 1-1.2.3: new full-speed USB device number 62 using dwc_otg
[3936714.491519] usb 1-1.2.3: New USB device found, idVendor=0483, idProduct=df11
[3936714.491537] usb 1-1.2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[3936714.491548] usb 1-1.2.3: Product: STM32 DownLoad Firmware Update
[3936714.491559] usb 1-1.2.3: Manufacturer: STMicroelectronics
[3936714.491569] usb 1-1.2.3: SerialNumber: 044737423438

The sketch works well. But in that sketch you could add lorawan tracker/mapper or both and a decoder to be able to use with ttn or helium networks. Googling, I saw that many users that ordered this board has trouble to make it work with lorawan, but I think that she is a great board for this job. It's small, has gps included and your sketch has oled working already. Only need to add some more info about join status and packets sent. Can you do it? Thank you for the great job.
