  i same set up with @yuza_tipo but i use UiFlow v1.10.5 i try run "module.get(module.LANBASE)" on putty serial, and getting error like this. Traceback (most recent call last): File "<stdin>", line 1, in <module> File "module.py", line 64, in get File "<string>", line 1, in <module> File "modules/_lan_base.py", line 33, in init File "libs/ethernet/wiznet5k.py", line 181, in init AssertionError: Failed to configure DHCP Server! Anyone have solution for this problem ? Thanks in advance.

  @felmue, it does not have the sticker, so I'm going to assume it's version 2 based on that.

  Felix, you were correct. All that was required was a cross-over of the white and yellow leads in the cable. Thanks. ...Brian

  @felmue You are right, it seems to be a voltage mismatch. The UART requests 5V, but ESP32 delivers only 3.3V. Reading: "On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI" Find more: https://manuals.plus/elechouse/pn532-nfc-rfid-module-manual#introduction Time to buy a M5stack reader unit and use the standard UiFlow drivers. Thanks!

  I think I probably have a defective unit. I have tried with only a single tab open, latest version of Google Chrome, tried it incognito mode also just to be sure some extension wasn't getting in the way. Despite all efforts it never connects to UIFlow. I know it's on the network because my router is showing it connected and sending/receiving some packets. I will probably stick with devices that have USB-C on them, this is way too much hassle and I don't want to have to rig up a programmer just to toy around with a prototyping device. Oh well, at least I'm only out $5.

  Hi Felix, thank you for your fast reply. I've used different Atmega, Attiny and STM32 based boards in the past, but new to ESP32. That's the reason for my "stupid" question. ;-) Thanks again.

  @srmobar said in Just a single M5Stack Plus-Module and no idea what to do: @ajb2k3 Thanks! Looking forward to additional tipps. My goal would be, to not require a core but to find a way to interact with it another way. If this is not possible, I concede :) I'm keen to try out different things and be it just for the sake of trying it. Can't be bad to learn a thing or two along the way While it’s designed for ‘Tara know, your not limited to M5Stack. You just need to understand the pin outs and communication method

  Hello @IndianaTux does that work with real loads (and not just the multimeter) attached to the output? I am asking because it looks like the MOSFET keeps conducting after M5.shudown() is called and only putting ESP32 into deep sleep (and by doing so reducing the current) makes the MOSFET to finally open. If my thinking is correct a real load on the output would keep the current high and thus the MOSFET closed. (I hope I am wrong.) Thanks Felix

  I'm sorry, the sample works! The problem was that the RFID2 return a different chip ID and takes longer to initialize, and my microBlocks library didn't expect that. Thanks for your fast response.

  Multiple M020 USB modules stacked?

  Hello @cyberluke not without hardware modification, I think. While SPI uses some signals (SCK, MISO, MOSI) in parallel for all SPI slaves, there is one signal for each SPI slave so it can be selected. In other words if you stack multiple M020 USB modules (w/o hardware modification) all of them would share the same select signal and therefore react at the same time (which is not what you want.) Thanks Felix

  Hello @Veto6017 thank you for reporting back - this is quite interesting. I used AT+COPS=1,2,"22802",2 to manually select UTRAN (2) instead of EUTRAN (7). Note: "22802" is provider Sunrise in Switzerland. BTW: AT+COPS=0 gets you back to automatic selection. Thanks Felix
