@robert-hh Es läuft jetzt. Ds Update ging nicht weil ich das Board für den Fipy überbrückt habe das es im batterie Modus läuft. nach entfernen des kabels ging auch das Update. Jetzt kann es weiter gehen. Danke für deine Mithilfe.

@brewnut When you take the voltage at the data pin, it should be about 3.3V. Do you have to visualize the data signal, like with a logic analyzer or Oscilloscope?

@robert-hh Thanks, I'll try that.

@ldbm we don't publish schematics of our products, sorry.

Thx @robert-hh !

@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.
