  Hello @emsea22 sorry, I don't have a tutorial. But no, you don't need to attach an FTDI dongle to the iEXT.IO2 unit - the I2C address can be changed via an I2C command sent from the host, e.g. 0xFF, <new I2C address>. (At least that is my understanding from reading the documentation.) Thanks Felix

  @m5stack Could you please correct the UnitCamForUIFlow firmware as follows? Set the WROOM-32 clock to XCLK=8MHz and the ov2640 clock to twice the current clock. This solution has been found by Sohtamei in the following thread; https://community.m5stack.com/topic/3649/unitcam-hw-issue-cannot-stream-video/8 Thanks a lot.

  Makes not difference if indoors or outdoors. Since it is connected to portA and not to portC as it is supposed to, do I need to make any modifications? Eg like here: https://community.m5stack.com/topic/1312/gps-unit-with-m5stack-fire-not-working/5 Thx

  @bartblommaerts said in multiple 4-Relays on same I2C bus: Oh the PaHub>2< Unit :/ its not available yet in the local stores. And the Pa.Hub (version 1) is sold out. You're better off ordering direct from M5Stack

  Hello @ve2dx try something like this: M5.Axp.SetLDOVoltage(3, 2500); the second parameter is the brightness. Max is 3300. Thanks Felix

  @aafortinet A mate of mine had the same issue -- seemed not to work until he used it within the 2-150cm parameters. The all good.

  The distances I get are really strange: The values are well below or well above the expected ones. For example, for a distance of ~95cm the sensor answers 4.5cm. For a distance of ~110cm, 4.9cm. For ~35cm, 3.7cm etc. The values change for the same distance. So different measures of ~200cm gives 13.7cm or 79.6cm the next time... The command Wire.begin(32,33) seems correct as I realize those are the ports for the sensor on the CoreInk. So, what am I doing wrong?

  Hello @drittich how is your experiment going? I ran a similar experiment where M5Paper would wake up every 10 minutes, connect to WiFi, make an MQTT call and then shut down again. Battery started at about 4772 and ended with 2920. It managed to wake up roughly 1200 times. So in my case it lasted about 200 hours. Now given that most energy is consumed when awake this numbers could also model your use case, e.g. 1200 times woken up, twice per hour would give 600 hours or 25 days. BTW: I assume by deep sleep you actually mean shutting down and wakeup from RTC, correct? Thanks Felix
