The modules are so far only accessible via the REPL run on a device.
I wrote a guide here that while targeted to the ATECC608b shows how to access real to find modules.

There are lots of ways to filter this type of data. The mean is one but you can also use median or an FIR filter. Take a look 🤗

I am designing a GPS disciplined oscillator and the goal is for a short-term stability to be better than 1 part per 10 to the 9th cycles. The uBlox GPS has 2 counter inputs. Approximately every second (1 measurement cycle) the GPS reports the count and the time of the last rising and falling edges on the counter inputs. These are reported to the nanosecond (10 to the -9 seconds). By subtracting the previous count and rising edge time from the current measurement you will get the number of counts and the time difference. From this you can calculate the frequency to approximately 1 part in 10 to the 9th. In the actual implementation you do this over a period of hundreds of seconds. In the example I gave the single precision calculation was in error by over 46 milliseconds. In a 1 second measurement this is approximately a 4.6% error! The problem arises because you are adding a very large number (5.31316281 x 10 to the 5th) to a very small number (657346 x 10 to the -4) and you need a result accurate to 9 decimal places not 1 decimal place. In the actual calculation these numbers were first scaled by a factor of 1000 and 1000000000 respectively so they were even larger numbers to start with. This code runs fine on a Pyboard with their double precision code. I would prefer to use a Core2 unit which has a much nicer display and form factor than the Pyboard and its display.
I believe the effort to create this new image is as simple as changing 1 definition to tell the compiler to compile code for double precision instead of single precision. If you interested here is a link to an individual who did this for the PI Pico. https://forums.raspberrypi.com/viewtopic.php?t=319525 For someone with the correct tools, knowledge and the source it appears to be a relatively easy task. Tools and knowledge I don’t have. In this case most of the effort would be in making people aware of the other firmware image and making it available for download.

Yes the baud rate is correct. The characters are not random. They appear to be a CRC error and it is being sent in hex rather than ASCII.
Anyway, I found that if I loaded the ESP32 generic binary file then it works. At least I can get to a Micropython REPL prompt. Of course, this version is probably going to me missing the libraries that I will need. I guess I will have to build my own binary version.

it fixed my problem with the crashes, but now i have no QoS 1

@robjasey said in Where is asyncio?:

So I tried help("modules") to get the list of all modules. Turns out there is a reference to "_uasyncio" but the object looks like it is only a shell of a module. It has references to a Task class and TaskQueue class but no functions. An attempt to use _uasyncio confirms this. Sigh.

Well that's a pain.
Sorry I can't help more.

The APs have 2ghz and 5ghz: wifi.scan show them here. it connects always on the AP with 22851-Gast Channel 1 with has really bad rssi -91 and not with the one 22851-Gast channel 11.
i think the logic needs to impore here. or i need do write a function which searches for the best one and connects to it.

(b'Labor', b'X\xc1z\xe5a\xc0', 11, -52, 3, False), (b'Phone', b'X\xc1z\xe5a\xc1', 11, -52, 3, False), (b'22851-int', b'X\xc1z\xe5a\xc2', 11, -52, 3, False), (b'22851-Gast'\xe5jA', 6, -68, 3, False), (b'Phone', b'X\xc1z\xe5jB', 6, -69, 3, False), (b'22851-Gast', b'X\xc1z\xe5j@', 6, -70, 3, False), (b'22851-Gast', b'X\xc1z\xe5l\xf1', 11, -80, 22851-int', b'X\xc1z\xe5l\xf0', 11, -80, 3, False), (b'22851-int', b'\xbc\xe6|^\x9f\x10', 6, -91, 3, False), (b'22851-Gast', b'\xbc\xe6|^\x9f\x11', 6, -91, 3, False), (b'Ph^\x9f\x12', 6, -93, 3, False), (b'Lager', b'X\xc1z"\xae ', 11, -94, 3, False)]

i tried to use "WLAN.connect(ssid=22851-Gast, password=dfsfs, *, bssid=b'X\xc1z\xe5l\xf1)" to connect to the bssid specific which good connection
but this is not working it says to much arguments taken

Not only that but the OLD password system has been upgraded to use certificates and encryption keys.

Currently my solution is that I wrote software that tunnels data between a virtual serial port and a real one, while displaying it to me. It uses com0com to setup the fake serial port.

Basically, m5stick is COM4, com0com is configured with fake COM6 and COM7. COM6 is connected to COM4 via my app and I can see the text in between them and inject keystroke too. VSCode talks with COM7 and all of the data from COM7 goes to COM6, to my screen, then to COM4

I also coded it so if I hit ESC, it sends the CTRL-C signal to the terminal so it brings up REPL. (pressing CTRL-C will quit the whole terminal lol)

This solution still sucks, exceptions are still printed to the LCD instead of to the COM port

wlan = network.WLAN(network.STA_IF) is 0_1654418854491_a0cdea9b-ae52-4361-82e6-68b7f114500a-image.png

i didnt used create station interface because of that wlan wasnt defined!

Thanks Felix

Check out UIFlow: How to try/except for "Connect to Wifi"?

Thanks for the response Flypeek, I've seen both those and nothing works. The M5Stack just reboots.

Found my error. I had flashed the M5 with a program of my own using Arduino. Using the UI Flow firmware, I get the Micropython REPL no problem with screen /dev/ttyUSB0 115200.
