  @shp96 That does not seem correct. Your gateway is only listening on channels 48 to 55 and 70... Can you show logs of packets received with the associated channel?

  Hi @johand, You probably won't have to update the bootloader, unless there's some bug or the OTA mechanism changes. We have no features planned for the bootloader at the moment, so you should be fine with OTA updates.

  Hi @bigboy20769 and @serafimsaudade, It has indeed been changed. Just to note that you're using development firmware while the documentation is based on the stable version. If you check the dev documentation, you can find the changed method. Once the dev firmware has been released, the main documentation will be updated as well.

  Hi @tanmay07, Could you check the firmware version of the devices? (os.uname()) What code are you running on them? Are you using WiFi, Bluetooth, or LTE?

  @ghelbig The latest firmware release is 1.18.0.r1. Try to update first. Then try to reset the device after the card was inserted. That help sometimes. If not, try a different, maybe smaller card.

  @calvinblock44 Sigfox enforces that the devices that consume their service need to be registered manufacturers, the Pycom's Sigfox native library contains sensitive information and code that need to be packed and secured (As more as possible). From there you have two options, construct your wifi sniffing functionality over the official firmware or select a more appropriate hardware that fit your needs. Be aware also that if you are planning to create a final product using certified boards your are not allowed to modify the RF code because is highly possible to void the certification if the code modify the way of signal emission.

  @xykon Can you list what bands are now supported? I've tried Band 8 using addscanfreq, but the device does not search for a network: CEREG is stuck at 0, "not registered, MT is not currently searching an operator to register to".

  @river In the loboris variant of micropython.org port there is support for the hall sensor. I tried that, just to determine, that the hall sensor is pretty insensitive. Better use an external hall sensor connected to a GPIO. The internal temperature sensor works, but has a huge variation form device to device. See the discussion here: https://github.com/micropython/micropython/pull/3933

  @marike Sometimes you have to do a hard reset with the SD card inserted to deztect the card. Also not all card brands and sizes work. And finally especially Windows does not format a clean FAT layout with a single partition.

  Hi @catalin Yes, I did follow these instructions. I did just that, and the usb device does not show. I also tried to repeat the dfu-util command with no success. I don't know if the hardware or is faulty (did not ls /dev or lsusb before updating the firmware to ensure that the hardware work). However, dfu-util does not work when the pytrack isn't connected, but it works when it is connected, as you would expect. I buggles my mind, how you can flash something that lsusb doesn't acknowledge. Do you have any suggestions? Best regards Frederik

  @xykon said in Change firmware from Lopy4 to Lopy1: @zceld I still suggest you contact us (I haven't seen any email coming in) so we can update you device details in the database. This way you will get the correct firmware updates in the future and don't need to manually download the correct firmware every time there is an update. I had not sent the mail finally because we had solved it so I thought it was already equal. Anyway, in a while I send it to you, it does not cost me anything. a greeting
