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?

@ajb2k3 Good to know. Thanks!

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.

Hi.
Excuse me I checked the documentation and also the github of M5Stack and I couldn't find the "MODULE_4IN8OUT.h" library can you provide me with the URL of the Library plss.
Thanks

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.

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.

It seems that FastLED.h lack of some developper to get it working properly on ESP32 now.
I jumped to AdaFruit NeoPixel lib and run this sketch successfully using your PIN values.

#include <M5Core2.h> #include <Adafruit_NeoPixel.h> #define LEDBAR_PXL 10 #define LEDBAR_PIN 25 Adafruit_NeoPixel ledBar(LEDBAR_PXL, LEDBAR_PIN, NEO_GRB + NEO_KHZ800); void setup() { M5.begin(); // put your setup code here, to run once: ledBar.begin(); ledBar.show(); } void loop() { // put your main code here, to run repeatedly: ledBar.fill(0xFF0000); ledBar.show(); delay(750); ledBar.fill(0x000000); ledBar.show(); delay(500); }

Hello @jorge5a

the COM.GSM can only operate with 2G networks. Are you sure in your region 2G is still operational? The fact that the SIMs work in a smartphone doesn't automatically mean they work in the COM.GSM as the smartphone could connect using something else than 2G.

That said you can try the following command. This will tell you if the modem has registered with a provider.

AT+COPS? +COPS=0 // auto mode not registered +COPS=1 // manual mode not registered +COPS: 0,0,"CHINA MOBILE" // auto mode registered

Or try to get a list of available providers.

AT+COPS=? +COPS: (1,"Sunrise","Sunrise","22802",0),,(0,1,2,3,4),(0,1,2)

Note: this command can take a long time and sometimes you need to issue it multiple times to get a result.

Thanks
Felix

Hello @swiminthesky

no worries. Thank you for reporting back. I am glad it now works for you.

Thanks
Felix

Thanks @teastain, @HWTaro9 but I'm especially looking for pcb footprint data like pad sizes and spacings to start with the pcb design.

Hello @jhashe

you are very welcome. An thank you for reporting back. I am glad to hear you got it working to your liking.

Thanks
Felix

Thanks for the support! I've managed to 'fix' it. Reinstalled the IDF with predownloaded V4.0.3 version.
I couldn't get the uint conversion working in the main.c. It came up with a lot of errors. So I decided to go for the quick and dirty solution; hardcoded sleep timer of four hours in microseconds. Not the way it supposed to be, but it works for me ;-)

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.
