  @ajb2k3 A deaktivated PIN code doesn't mean that the SIM card is deactivated. SIM Cards are normally designed for cell phones and the provider gives you a new SIM Card locked with a PIN code and a PUK Code. (3-5 times entering a wrong PIN code blocks the SIM card and you have to enter the correct PUK code to unlock the SIM card. Entering a wrong PUK code several times will brick your SIM card and you have to get a new SIM card). Putting the SIM card into a cell phone the first time you will have to enter the SIM card PIN in order to unlock and to have access to the the SIM card. You can also use a PIN locked SIM card in an M5Stack GPRS/LTE module sending the right AT-command with the PIN required to unlock the SIM card. An easier way is to deactivate entering the PIN every time at startup with a cellphone: Put the new SIM card (per default locked with a PIN provided by the SIM card provider) in a cell phone, enter the PIN in order to access the SIM card. Then, in the cell phone setup menu: allow using the SIM card without entering the PIN code when you turn on the cell phone . (You normally protect the cell phone with a separate PIN code, so you don't want to enter 2 PIN codes every time you turn on your cell phone) . Now the "PIN-unlocked" SIM card can be used (and is active!) in an GPRS/LTE device without entering the PIN code. I have been using this routine regularly for the SIM-Cards I put in my GPRS/LTE WiFi mobile router, giving me internet access when I am away from home (I don't trust public [sniffing] WiFi networks ...). PS: Putting the SIM Card into a cell phone also allows you to change the PIN code provided with the SIM card eg. "1234" to "0000".

  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.

  @ochoadavid Hi, David maybe you can help me, my problem : how a hell I can send the "Ctrl X" to the GRBL with the "Write G-code" block? I spent 2 hours with different approach without any success. Thanks to any idea. Best regards, Péter

  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.
