  Hello @Costas from the scan result I suspect you are using an M5Core2, correct? The M5Core2 has an internal (GPIO21/22) and an external (GPIO32/33) I2C bus. Right now your code scans the internal I2C bus, but the SGP30 is connected to port A (external I2C bus), so you need to change your code to scan the external I2C bus. Thanks Felix

  @ajb2k3 Kind of. I am using push of data in a time-based function (UIFlow). Tried normal and async save methods of a string and an integer. The Atom then freezes without transmission and the function is never terminated. Previous Firmware 1.9.7 allows continuous transfers of two values and reverts to the main loop after finishing the function.

  Hi guys in UiFlow the IoTBaseCatM module can only be used if a SIM card has been inserted. In other words the non IoT related ports (e.g. Modbus) cannot be used w/o SIM card inserted. The reason for that is that as part of the initialization catmiot = module.get(module.CATMIOT) an AT+CPIN? command is sent every 6 seconds forever since w/o SIM card inserted the response from the SIM7080 is ERROR. Thanks Felix

  Just for completeness, I'm on a 2021 Macbook Pro M1Max with 64 GB of RAM and macOS Monterey 12.3.1. I've tried it using Python 3.9.11 and 3.10.3

  Hello @IAMLIUBO the MQTT block fails when trying to connect to HIVEMQ broker using SSL. I found that for a successful connection an additional parameter server_hostname in the ssl_params is required. Please see this post. Thanks Felix

  @iamliubo said in UIFlow 1.9.0: @felmue Now the button move to the bottom right,one is call "Run" means the workspace's code only run once,if you reboot the device code won't run again,and another one call "Download" means downlaod the workspace's code to the device filesystem and run, the code in the deivce won't disappear when you reboot or somethings. In a word, "Run" button is recommend for developing mode, and "Download" button is deploy after develop. Hello @IAMLIUBO understood, but that was not my point. I am only talking about the "Download" button which when pressed shows a popup saying "Uploading". but it's really just a cosmetic issue - don't worry about it. Thanks Felix

  @felmue said in UIFlow 1.8.6: Hello @Phuturist using UIFlow 1.9.0 works for me (well kind of). With M5Core2 I can use the whole LCD unit screen (eg. 135 x 240). However with M5Atom (or M5StickCPlus) I can only use part of it, else there is an out of memory error. Here is what works for me with M5Atom. Thanks Felix Thanx Felix, it's indeed now working for a small partion of the screen when connected to my M5StickC Plus. Trying to set it to it's actual size indeed results in a memory allocation error. I had seen that one before as well but didnt think it was related to the screen size. If anyone knows how to fix the memory allocation error, please let me know.

  I saw the firmware issue comping ages ago. @m5stack this is why I recommended you build a firmware customiser that only builds the firmware with user selectable modules. You were going to run out of capacity trying to support all the hardware options in the way that you are currently trying.

  Hello @m5stack it looks like there might be an issue with the Vibration Motor Unit which only runs very slowly or not at all when using the dedicated blocks. However when using the analog output directly it works. The difference is with the dedicated block the GPIO output doesn't go higher than 0.5 V whereas with the analog block it goes up to 3.3 V as expected. Note: I personally do not have a Vibration Motor Unit - my conclusion is solely based on looking at the schematic and measuring the GPIO output of my M5StickC Plus using either of the aforementioned blocks. However user @dailletaille verified it to work with the analog block, so please also see this topic here. Thanks Felix
