  @aen I had a different experience. This worked for me: >>> import sqnsupgrade >>> sqnsupgrade.info() <<< Welcome to the SQN3330 firmware updater [1.2.6] >>> >>> FiPy with firmware version 1.20.0.rc13 Your modem is in application mode. Here is the current version: UE5.0.0.0d LR5.1.1.0-46470 Then on the terminal: >>> sqnsupgrade.run('/dev/ttyACM0', 'NB1-41019.dup') <<< Welcome to the SQN3330 firmware updater [1.2.5] >>> Firmware file is too big to load via FFF method. Using ON_THE_FLY Attempting AT wakeup... Session opened: version 1, max transfer 8192 bytes Sending 5835531 bytes: [########################################] 100% Waiting for modem to finish the update... <<<=== DO NOT DISCONNECT POWER ===>>> Resetting............................. Your modem has been successfully updated. Here is the current firmware version: UE6.0.0.0 LR6.0.0.0-41019 When I tried your method (to upgrade) the result was an error: Upgrade failed with result failure[diffUpgrade,239] Patch didn't apply! So I figured I'd just upload the final image rather than a diff as the factory shipped firmware appeared to be some unknown number (46470) The documentation on all this is convoluted when its probably quite simple.

  hi @pytrackuser1 and @jcaron I've run an similar experiment, on Pysense, for some 12-14 hours and it didn't failed (sleep cycles were 20sec). I've used a 2Ah battery, and recharge it once during the experiment. I've met such situation, but the battery was weak, 3.6V showing on pysense.read_battery_voltage(), indeed it did not wake up. You could log into NVS last value of: the battery voltage, number(count) of restart, time from RTC, maybe we notice a pattern. Computer could go into in standby, and minimise USB power source; but you said you've used a power adapter... One question, after the block, you just cycle power and it works fine, isn't it? OK, I will try to monitor power usage, maybe I can detect something. To disable Pybytes: we’ve just released v1.20.2.rc3, which supports the method pycom.pybytes_on_boot(False) for the previous versions, there are 2 commands: >>> pybytes.smart_config(False) >>> pybytes.set_config("pybytes_autostart","false")

  Dear Robert, @robert-hh said in G01 power consumption: Without LTE init, the current drops to 20µA too. Are you saying that the LTE shutdown magic by invoking lte.deinit() referenced many times in the forum will not be required at all? Our scenario is that we are currently not using the LTE modem of the FiPy and want to get power consumption as low as possible. We are humbly asking for your experience here, especially with the latest firmware releases. Also, I just stumbled over lte.send_at_cmd('AT!="powerOff"'), which also does not sound that bad ;]. Maybe this will shut down the modem in the quickest way possible without going through all procedures of the regular lte.deinit(). Thanks already for taking the time to answer our question on this evergreen topic. With kind regards, Andreas.

  @KenM So easy. Sometimes you have to know for sure that there is a big in the code, to be able to see it.

  @Alephus Loyp Just scale them properly. You may also take the raw ADC readings and do the conversion yourself. But I would add a voltage divider between you gas sensor and the ADC input, such that the input never gets a value > 3.3V. That divider could for instance constist of a 10k (between ADC Input and GND) and 4.7 K (between ADC input and sensor output) resistor, with an additional 10nF capacitor between ADC input and GND. The scaling factor would then be 1.47 (if you read 1V, the actual output value is 1.47 V).
