  @kjm said in new error msg with little fs: Does your vanilla still have adhoc wifi? I wouldn't know otherwise. However, I haven't personally tested it.

  @kjm I don't believe so. It will just reformat the user space filesystem mounted at /flash. This is completely different from more lower level operations like erase_all.

  @sksolutions Without going into depth, that's what I understand from the code: the timer itself is a 64bit quantity. That value is divided by the clock frequency and returned as a float. max of 64 bit / 160MHz gives 115 292 150 461, or about 115 billion (seconds, ~3665 years). The granularity is diminished by the fact, that the number is returned as float. So about 100 days after start of the device you will loose seconds resolution. But my experience tells that a typical device will anyhow tip over before that and has to be rebooted.

  @tari4a1i_iaos This issue is with the HTTPS connection. I tried using a HTTP connection and the program works fine. Just wanted to updated here so that if anyone else is looking for a Proxy architecture this works fine. I am still having trouble in connecting HTTPs but will open up another ticket on that. Thanks, SYED

  NBIOT With AT&T In US

  We've tried multiple options with no luck attaching to the AT&T network using the current GPy NBIOT modem firmware using an AT&T SIM provisioned for NBIOT communication. We've tried bands 2, 4, 12, and also not specifying a band. It's our understanding that the APN to use is the same as what we use for CAT-M1 (10569.mcs). Other than specifying the band in the attach command, are there any other differences between using CAT-M1 and NBIOT?

  Dear @psrebrny, @psrebrny said in 1.20.0rc13 guru meditation: I also got this type of error, when executing my code. Did you have the chance to run your code on our custom build [1] already and do you observe any difference? With kind regards, Andreas.

  @robert-hh said in OneWire.py problem: The [refurbished] driver is here: https://github.com/robert-hh/Onewire_DS18X20. It follows the API of the native MicroPython driver. Taking this chance, we want to thank @robert-hh so much for taking care of all the details regarding this driver. It was a real pleasure to work together with you getting this a real home and - to top it all off - big thanks that you also made its API match the one of the native driver, so people can swap them in and out. We have been doing this through [1] already and are very happy about it. [1] https://github.com/hiveeyes/hiveeyes-micropython-firmware/commit/2a23af47

  Dear @tanmay07 and @Martinnn, if you feel lucky, you might want to try our custom build just released on [1]. More background about this is available through [2]. Please be aware that when upgrading from a lower firmware version to this custom build based on 1.20.1.r1, you will have to erase your device completely before flashing in order to keep things straight. You will find respective references to this on the forum. Hint: Use pycom-fwtool-cli --port /dev/ttyUSB0 erase_all, see also [3]. With kind regards, Andreas.

  @kjm said in GPY crash within a crash: I'm gonna stick with the 1.20.1.r1 Robert did for me for a little while, it has adhoc wifi by default plus I'm in the middle of chasing down a bug @kjm said in GPY crash within a crash: I don't like to change firmware mid hunt I understand that. However, we’ve just released another bunch of firmware images with hopefully improved robustness, so [1] might make you happy. If you feel lucky, you might want to try this and we will be happy to hear about the outcome from you.

  I was using a hologram Sim, I will paste code as soon as I get to my home computer, Essentially the issue I was having was with the uMQTT library. When i would compile the code it would say "Can not import Umqtt"

  @robert-hh said in ram alternative to nvram?: Having the RAM disk mirrored to RTC memory is hardly usable, since the size is limited to 2048 byte. Thanks for your investigations revolving this and for letting us know about the outcome!
