      Thank you.

      What is the content of sqnsupgrade.py as shown in Visual Studio?

          Umm that's definitely not right. Should be Python code.

          Can you try downloading it again? It's better to download the whole project as Zip from Github and it pick it from there. I think you chose to save the webpage instead.

            That was really a critical error on my part, I apologize . I have downloaded all the files again looks the same as on Git.
            I have the two *.dup files under /sd directory in my microSD card.

            >>>import sqnsupgrade
>>>
sqnsupgrade.run('/sd/FIPY_GPY_CATM1_33988.dup', 921600)

              Glad you got it going so far.

              Are you saying you placed the files into a folder called sd on the SD card? That's actually not necessary, the files should be directly on the root folder.

              The /sd is just a mount point for MicroPython

                Now I get AT+SMSWBOOT=3,0 failed.
                I removed the sd folder from the SD card, formatted it again to FAT32 and SD card now contains just the two *.dup files for CAT-M and NBIoT only on the root.

                On executing the following from main.py or from REPL I get the error:

                  OK it's reading the files correctly. Can you try a couple more times? Make sure it's from a clean, freshly power up, start.

                    Ok repeated the following steps in order:

                    1. Ran os.mkfs('/flash')
                    2. Powered off Fipy/Expansion board 2.0
                    3. Took out SD card, formatted the SD card and reloaded the CATM 's dup file into it.
                    4. Powered Fipy on Expansion 3.0

                    Tried about 4-5 times now and about 3-4 times earlier to you reply.

                    The FiPy is on a Expansion board 2.0 and powered via the USB connection to the PC.

                      Ok thanks, can you let me know the output of

                      from network import LTE
lte = LTE()
lte.send_at_cmd('ATI')

                      Thanks

                        Sorry just saw you're using the Expansion Board, have you removed the CTS and RTS jumpers from the board?

                        When using the expansion board with a FiPy, you will need to remove the CTS and RTS jumpers as these interfere with communication with the cellular modem.

                          I took out the CTS and RTS jumper at the start itself, rest of the jumpers in place.
                          The unit is not responding to

                          lte=LTE()

                          its hangs up, first time it was stuck for over 3 minutes that's when I did Ctrl-C to get out of it. Tried again and its stuck again and won't respond to lte=LTE()

                            So lte = LTE() doesn't respond? Even from power up?

                            If so please open a ticket with our service desk so we can best handle it.

                              Finally responding now after a few power-ups.
