@eric-waai Yes it was a typo I have 3 i2c devices

@fedesilvi Just to give you an impression how bad the esp32 ADC is, I collected 10000 samples with the ESP32 ADC and an ADS7818 ADC taking values the same LM385 voltage reference. The absolute values differ, because of the different ranges (5V vs. 3.3V). The histograms are below: Edit: Adding a 10 nF capacitor close to the ESP32 ADC input and switching off WiFi improved the picture. The one above was WITH the capacitor. Without, the capacitor, it was worse (avg +/-100 readings)

@dr_aloui In that case it's strange. You you have an oscilloscope to look at the signal timing? The expansion board should not add any significant load to the wires, at least not to P9 and P10. The Pyboard has built-in pullup-resistors on the pins dedicated for I2C (X9/X10 and Y9/Y10). That could makes a difference.

I have email send method implemented in my MycroPython port as a part of the curl module. I think it could be easily ported to Pycom's MicroPython (curl_mail.c, modcurl.c)...

I can confirm same behaviour with LoPy4 running FW 1.18.1.r1. Difference in RSSI in my case is more than 20dB because the module (and its integrated antenna) is enclosed in aluminium housing.

@fedesilvi I recommend you try PySimpleGUI It's much easier to program a GUI in PySimpleGUI than PyGame. Do you have tkinter on your platform? You should be able to hook up your GUI to anything you want. To display your information, read the data using your code, then plot the data using a Matplotlib / Pyplot call. You can then display that graph in your GUI. There is extensive documentation on how to use it and there are several example programs posted the demonstrate hooking it up to Matplotlib.

@gda45-78 Hi, don't you have loaded a back WLAN process on the board that consume too much ? (see your post 3 months ago in your profile). regards.

Hi @klaus, Currently, you can only configure one WiFi network, and save multiple in the Pybytes console.

Hi @fbt said in problems with service_data field on advertisement packets: it is possible to configure the wipy not to send those fields? Sorry, this is not yet possible.

@soulsurfer That's the lib which is existing, from the genuine micropython in the micropython.org branch. You may use it, it requires uasyncio, uasyncio.core, uasyncio.queues and uasyncio.synchro. In uasyncio.core you have to make a small change in line 73: in the call to ticks_diff() you have to swap the parameters. I did just make a few basic trials, like running a coroutine.

@jmarcelino Hi, I used a WiPy 3.0.

@inverseeffect Did you ever get any resolution on the keepalive timer? I'm running into the same issue. For now I've switched to simple.py, but I would much rather use the AWS library.

There might be something in the code to change it but that would require compiling the firmware etc so its probably easiest to stick with the python library

@nicobijl Interesting use case, though you'll be faced with reflections and multipath which may give you false results, depending on the exact layout (and most importantly, distances). Also, you should check the gain of your antenna in various directions, it's not because it's "concentrated" in some directions that it doesn't receive anything in others. Note also that if you do anything that transmits (active scanning, which I believe is the default now?), using a directional antenna means more gain, which may bring you above the allowed TX power threshold (depends on your region). Conversely, at short distances the high gain main saturate the receiver. Finally, one would need to check the exact radiation pattern, but I'm not sure 4 such antennas would be enough to cover 360°, they have a relatively narrow aperture. Let us know what you find out!

@hypercoffeedude I do not use blynk but few things are you sure that you have not more BlynkLib on your flash? What is exact error message - all python messages point to line number with error. On your post you show only AttributeError: 'module' object has no attribute 'Blynk'. this lib is for Wipy1 (maybe there are some differences) - but error message is not releated to this
