  I just experimented with how to solve the problem. (1) I disconnect the base of M5Stack Fire (it is labeled M5GO) and uploaded the same program many times (until the Fire became "hot condition"). It seemed OK. (2) I docked the Fire to the original base and uploaded the same program many times and again the issue appeared. At least in this stage, I can conclude (without knowing the reason) that the base of the M5Stack Fire (M5GO) may be the cause of the problem. The other possibility is that by disconnecting the base, no power is supplied to the core so that everything is reset and things go to normal. I do not know.

  @butch said in Identify M5Stack Fire Revision & Issues: @jpk Was there ever any response / resolution to this question regarding Fire Hi Butch, not really. But they put some more informations on the webpage. Which does not contribute to clarify things. @m5stack @lukasmaximus In the mean time there are a lot of modules and there is more and more documentation. But the documentation is really a bit annoying and not always clear...Questions in this forum are not really answered. Initially I really was impressed by the m5stack, but this lack of quality/documentation is a bit disappointing. Want an example? Maybe you can sort it out (b.t.w it is still the same question of the first post in this thread): 1.) Revisions (new information on the page) See this page, scroll down to "Version-Change" https://docs.m5stack.com/#/en/core/fire?id=version-change But surprise, my PCB revision ("2018. 2A") is not even listed.. :-? According the numbering scheme I own a PCB before "Initial public release" (or it is hex_2A=dec_42?)...? 2.) I2C Adresses used by the equipment https://m5stack.oss-cn-shenzhen.aliyuncs.com/image/m5-docs_table/I2C_Address.pdf The "Fire is not explicetly listed here, but it should be part of "M5Core" section. Again: Revisions (see 1.)) are not taken into account here. ==> Based on this information (0x68, see first post) I should have a MPU6886 (=latest 2019 PCB revision acc 1.)) installed...? But this does not match the fact, that I have an old and undocumented PCB revision... 3.) As the "MPU9250 Basic Example Code" is working for me, I assume I have a MPU9250 installed, which again acc. 1.) would mean I have a PCB revision "2019.7". 4.) In the "official" (?) store https://www.aliexpress.com/store/product/M5Stack-NEW-PSRAM-2-0-FIRE-IoT-Kit-Dual-Core-ESP32-16M-FLash-4M-PSRAM-Development/3226069_32847906756.html?spm=2114.12010612.8148356.5.1adc593auFAMct There is still written "9DOF: SH200Q+BMM150", even though the latest version should be "MPU6886" acc. 1.) Confused? :) jpk

  I had similar problems, here you find my way for solving these I made a hour counter using UI-Flow. When i test it using the run button of UI-Flow it works fine, but when i try downloading the program to the m5stack it also freezes. After adding more program code, the testing also fails because the py-code where re-sorted by UI-Flow and some procedures where located at the end and are not reachable for the main loop. After manually sorting the procedures in a correct order the program runs fine again but downloading is again not possible. The cause of this behaviour is that UI-Flow stores the complete blockly-file (.m5f-file-type) in addition to the py-code to the m5stack. Therefore i used vs-code to transfer the py-code directly to the m5stack without the blockly-file and the program runs. My conclusions for big programs: they will be resorted by UI-Flow in a unexpected manner they can't download with UI-Flow, i belive the cause is located in a memory limitation but they can be transferred by using vs-code, to do this see also the m5stack video: https://www.youtube.com/watch?v=Y9pOWgsNgKk

  @lordinchcape if you want compiles quickly, you should use platfromIO. Not Arduino IDE

  Hi @Efried are you using micropython/uiflow firmware or arduino? make sure you have installed the cp210x drivers first if you haven't already https://m5stack.com/pages/download I made a few simple tutorials on hackster.io to get started with http requests, hope they can be of use to you. https://www.hackster.io/lukasmaximus89/m5stack-and-mit-app-inventor-47bd32 https://www.hackster.io/lukasmaximus89/m5stack-micropython-simple-web-server-20a4c4

  Due to hardware flaws, sometimes when interfacing with some of the units there is an audible hiss. Unfortunately since it is a hardware flaw the only solution is to use code to reduce the volume of the hiss. in Arduino it should be something like dacWrite(25,0) Python dac0 = machine.DAC(25) dac0.write(0)

  Hello @Yova, there is a standard library for SH200Q available for the M5Stick. Since I have a M5Stack Fire core, I ported this library in order to work for this device. You can find it at the address: https://github.com/scavallero/SH200Q. I will put there an example as soon as possible.

  @grelm I would normally have said the adafruit libs but I keep reading that fastled is well, faster. If you look in the docs there should be some listings for the pin outs but normally RGB leds are connected to Grove Port A the red port.

  M5Stack FIRE - should I return it?

  @fonix232 said in M5Stack FIRE - should I return it?: the bottom boards seem to be swollen as well (the bit where the battery is connected to the PCB is pushed and warped upwards, making stacking quite difficult and in some cases, impossible). Seems odd. Can you post a picture? Maybe it’s a result of a swelling battery. There were also some battery issues earlier with their vendor/supplier. Either way, the M5Stack team provides good customer service. I’m sure they will address your problems.
