That question of which sensors to use is dependent of environmental conditions. In My case an RPI acts as an MQTT server (because I have one available), controllers capture the data from the sensors and send them Over WIFI to the MQTT on the RPI using very simple UIFLow code. This all depends on wifi range. I do have a sim module to review but I have been struggling to understand and find suitable SIM cards for MQTT/IOT use.

Hi @felmue No, the example server works fine. You are right, it was probably an issue with csv reading. Thank you

Hello @Leo05 hmm, not sure why GPIO27 didn't work - it's marked as GPIO on the M5 Bus - should be free to use. I assume you've set it to output first? If you're not stacking a module which requires a serial connection GPIO13 and GPIO14 should be usable too. If you are not using I2C on the Groove port then GPIO32 and GPIO33 should be free too. Also GPIO35 and GPIO36 are free, afaik, but those two can only be inputs. Thanks Felix

Hello @Leo05 have a look at the schematics of M5Stack Core and PLC. I do not have the PLC module but I do have the LAN module which is similar in that respect and I do have both 12V and USB connected at the same time while programming the M5Stack Core, but not permanently. Both power sources produce 5 volts but there might be a slight difference in the voltage which would mean one power source is feeding a small current into the other, but I don't think it will damage anything. Nevertheless, use at your own risk. The full project, M5Stack Core and PLC module will work fine from USB only. Unless you add something in the PLC module which requires 12 volts. According to the PLC module schematics the BAT pin is not connected / used. But it will show the battery voltage from the stacked M5Stack Core. No, the battery in M5Stack Core will not charge when only 12V is applied. Only USB can charge the battery. Thanks Felix

@lukasmaximus I send it to support@m5stack.com on Nov 1. Tahnk you for your answer, I will recontact, not urgent. I understand the workload! you made a great product everyone want ;)

@noiseislife said in Dices example not working on M5Stick C: To get around this I saved the Example sketch to disk, deleted the file Dices.ino and then opened Dices_MPU6886.iso. You will get a message about requiring that the directory name be changed, which it does for you. You should now be able to successfully compile the sketch to the m5stick. Thank you. Now it works !
