  @felmue ..Thanks for that a colleague sussed that out just before I read your reply but many thanks as you were dead right... as all up and running now. For anyone reading this reply the illumination of the centre main on/off button is LED #4 I didn't realize that the LED's are multi colour until I studied the circuit diagram/schematic ...cool !

  Hello @FLOSCH the reason battery level, power, voltage and current are incorrect is that the calls to GetBatteryLevel(), GetBatPower(), GetBatVoltage() and GetBatCurrent() are happening before I2C is initialized and therefore return invalid values. You'll need to do this calls inside setup() and after M5.begin(). Thanks Felix

  Hi, Sometimes I find IPX (or I-PEX or U.FL?), sometimes MCX, sometimes SMA... on descriptions So I link them all here... so you can find out yourself SMA wikipedia the most common one, it is threaded MCX wikipedia snap in IPX I-PEX U.FL wikipedia very tiny, mostly used on little pc board connections, surface mounted, snap on For antennas, you could do an internet search with keywords: "868 MHz antenna" Also YouTube is a nice source for searching all these terms LoRa module video on YouTube at 2:00 minutes it shows internally U.FL connectors, and externally MCX if I am not mistaken

  @sasoo The code by christianc is incomplete and does not work The AT+CRX and AT+CTX are test commands, not meant for this application, and take your asr6501 in a dead loop, see documentation When doing this with an antenna connected, you might transmit without knowing you do, and cause interference for others In fact it seems Peer to Peer LoRa with asr6501 is not possible, it is designed for only LoRaWan, if I am not mistaken... from documentation: Notice, When enter into CTX Test, system enter into dead-loop, if you need other test then reboot the board for the next other test command. from documentation: Notice, When enter into CRX Test, system enter into dead-loop, if you need other test then reboot the board for the next other test command.

  @sippanan_p It seems that your band frequency is OK for US, so do not worry about setting the RX window? Maybe not able to join has another cause?

  Would love to know if there is a fix to have this work with the core2. I just purchased a core2 and the driver module, just found your post after many failed attempts with the same error you got.

  For anyone finding this. I contacted M5 and they suggested the odrive module, but that's currently out of stock. I've moved on to trying to use either a stepper motor or a servo for my application and I think I can make them work.

  Bump. Me too! I can't find an M5 copy of MLX90640_API.cpp and MLX90640_I2C_Driver.cpp. After commenting out calls to MLX90640_BadPixelsCorrection() I tried using Sparkfun's version, but the .ino file has calls to interpolate_image() and get_point() which the Sparkfun library does not have. I tried using Blockly but the data returned by the calls to unit.get(unit.THERMAL, unit.PORTA) objects return garbage data. Well, not quite garbage - it's data but it is not corrected and interleaved in a way I can figure out. Micropython might be a better bet but I don't know how to get the Unit libraries. I don't have a spare Arduino to test on either.

  @jptalledo I have noticed it drains the battery of the M5Paper quite quickly. I have not tested that specifically as it was not a requirement for my project. The range is quite good at 50-70 cm. I think there is a way to change the power and read strength, though I have not investigated too deeply. I am using other methods to alter read time. When I get to a stable point I will refine some more.

  Hello @thop in UIFlow online check out Base - Motion. On the Python tab you'll see how to use it with MicroPython. Thanks Felix

  Yes, you would send position or speed values to each channel. There should be an example in the documents. If I misunderstand let me know and I will research further. Arduino IDE, no problem, and I’m sure it is facilitated in UIFlow.
