  Hi @Tarun-Nigam Are you running this on a Raspberry Pi? I think VS Code on Raspberry Pi is very new. Can you do Pymakr > Extra > List Serial Ports and tell me what is says? I think on the Raspberry Pi only 1 of the USB ports is a Serial Port. Have you tried it plugging in to a different USB port? Matt

  @Anthony-Leung I suppose the firmware or the underlying ESP-IDF starts the dhcp server when in AP or AP+STA mode and doesn’t stop it when you switch. Not sure if there’s anything you could do from your micropython code to stop the messages, but I would believe them to be pretty harmless, though one would need to recheck the code which prints this. Things you could try include switching off WiFi via WLAN.deinit() and then switching it on again. Or worst case, reboot the board between the two modes.

  OKAY! The problem has been solved by adding a receive policy to the group the thing belongs to. { "Effect": "Allow", "Action": [ "iot:Receive" ], "Resource": [ "*" ] }

  @mogplus8 P5 and P7 are fine. The ADC's are limited to 8, P13 - P20, since only ADC1 can be used. P4, P8 and P23 are connected to the SD Card adapter on the expansion board. If you want to use the SD card, you cannot use the for other purposes. Otherwise you can use them. The USB is connected through a USB/UART bridge on the expansion board to UART0 on P0 and P1.

  Pymakr in VSCode can't find NodeJS (but it is installed)

  I've determined so far (by a small hack to pycom.pymakr/pymakr.js after installation) that the PATH that VSCode receives does not include /usr/local/bin, where the "node" executable is installed. (VSCode is being launched from Finder.) So the problem reduces to how to get that PATH into VSCode, which appears remarkably difficult in more recent versions of MacOS, and none of the recipes I've found work reliably without manual intervention. Moving node into /usr/bin is not possible due to MacOS System Integrity Protection. I can at least use pymakr now, but the extension or the installation instructions need to be updated to provide a workaround for this issue.

  @fernandes-son That would be consistent with what I believe the code does. The AU915 region only sends join requests at SF12, which take a long time to send, and are thus affected by the specific duty cycle. Some other regions can use faster data rates which mitigates the issue, depending on what data rate is used first. Is there a specific reason this is an issue for you? Normally a device just joins once and after that it doesn't need to do it again, so it shouldn't be a big issue. You may try restricting data rates on the channels, but I wouldn't be surprised if the code actually enforced the DR0 rule for joins per the spec.

  Thanks @pedroknup it works, but for some reason it has to be enabled manually over and over again.

  Dear @sita, @ps47 also experienced similar errors like you have been observing [1]. He is also using pure LoRa. Using the most recent 1.20.2.rc3 release seems to help here [2]. Thanks @husigeza and the whole Pycom team for mitigating this issue. I tried the new build LoPy4-1.20.2.rc3-0.8.0-vanilla-squirrel.tar.gz and not any “bad00bad bad00bad bad00bad” Core Panic happened till now. With kind regards, Andreas.

  @jcaron Thank you for answering. My question is not about WPS which is also a very interesting topic anyway or smartphones applications. My question is about GPS and L76 chipset as implemented on the PyTrack. Indeed WPS helps GPS to get quicker resolution. I do agree with you the PyTrack library is very crude, thank you for the last link, this one is helpful.

  @goldfishalpha No, I just moved the txt-files outside the project folder. That is good enough for me. Johan
