Re: Checking WiFi strength?

That works! Thank you! If I may ask, where can I find the complete official doc for wlan? Is the following it? https://docs.micropython.org/en/latest/library/network.html I thought I should look under ESP8266 and/or ESP32 but didn't realize under network library there are these very brief descriptio...

Checking WiFi strength?

I wonder if there's a simple way to check the dbm value of wifi reception on MP. According to the doc, there's a scan() that returns a list of access points. Here is what I got: (b'my_SSID', b'\xd8\x07\xb6\xd8\xc0/', 5, -34, 3, False) I wonder if the -34 is the dBm. Can I get the strength of specifi...

Re: ESP32 micropython support of W5500 Ethernet

Thanks. I am just a developer, not very well-versed in git. I have no idea how to do this. I have cloned micropython and micropython-libs and just pulled from master. I can also build python. I did that a few times so I can refer to my notes and experience using IDF. Then if you could point out to m...

Re: ESP32 micropython support of W5500 Ethernet

Not sure the progress. The git pull comments are too technical for me. Any update?

Re: Trying SSD1305 display from adafruit

Maybe there's a reason for such incompatibility. Adafruit sells ssd1305 displays and their libraries are circuitpython/arduino. If they wrote micropython libraries I bet their sales will likely drop. They have circuitpython only running on their own boards. Maybe ssd1305 is their turf.

Re: Trying SSD1305 display from adafruit

Seems to be driver issue. I tested with Arduino IDE and adafruit libraries and the display worked fine. I wish we could get an SSD1305 driver for mp. You can do many project if you have a display.

Re: Trying SSD1305 display from adafruit

So here is another SSD1305 display I was running SPI on. You can see the streaks run all the way across the vertical dimension from the characters to the bottom.
