Solved, Powersupply causes the Problem! DHT22: 3.0V >= Vcc <=6V ESP12: 3.0V >= Vcc <=3.6V FTDI-Powersupply (PS): a) 3.1V b) 3.5V I think the accepted low/high potential between both units are in a critical situation. It works with PS b) It fails with PS a) Using 5V (USB) for DHT22 and reducing the ...

Failed to read sensor: Errno [110] ETIMEDOUT

Hello, I've tested my new ESP12-F with the well known 'blink.py'; it works. In the next step I have this code: from machine import Pin from time import sleep import dht sensor = dht.DHT22(Pin(14)) while True: try: sleep(5) sensor.measure() temp = sensor.temperature() hum = sensor.humidity() print('T...

Thanks for answering again! The len of request = conn.recv(1024) is 375 Bytes (nice to know) 8-) A simple print('Content =', request) doesn't make the result better. Trieing print('Content = {} {}'.format(len(request), str(request))) shows that it is impossible to do this print with ESP8266/D1mini p...

Hello! I use this codesnippet at the end of my AP/STA Template. Further Connecting WLAN (ssid, pwd) is successfully done. # Connecting to WLAN, reading sensors, making webpage are done 1 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 2 s.bind(('', 80)) 3 s.listen(1) #only one client 4 while T...

Ok,the small RAM (<36KB) might be a problem. But I think I don't understand the solution and have tried this: I open the bme280.py (or any other library) and download this file into the device. I do not run it (F5)! BMP280 (7kB) is a Sensor for Temp + Press; BME280 (11kB) is a Sensor for Temp + Pres...

Hello, I've some programms running well in an ESP32 environment and I want to run them on a D1mini Pro (16MB) with ESP8266 firmware (flashed by uPyCraft). Several Problems occur. One of them is this: import bmp280.py is ok. I get at last the answer >>> import bme280.py fails with the answer: downloa...

Well,
'I'll kill that ...' AP.

Thanks to both!

stay healthy!

Hello again!
Moments later I recognize that I've scrolled over the solution:
>>> import webrepl_setup
I set it to 'D' and restart.
AP seems not to be running but is still available in WLAN.

Thanks

OK! 1.6. WiFi: 'WiFi configuration will be discussed in more detail later in the tutorial.' Where is later? 2.2. WebREPL - a prompt over WiFi The benefit should be an alternative to the known commandline. Actually I'm logged in (ipad) but can't get access (192.168.4.1). I try it later. And (hence?) ...
