Hi, i want to use a digital potentiometer on a m5 stack powered with loboris firmware. I also have an adafruit DS3502 lying arround but only found circuit python drivers for the device. Does someone have a glue how to talk to that thing? This is the circuit python driver: https://github.com/adafruit...

I would like to bring up my question cause i really like the h801 boards. My solution so far is to solder a very thin wire to a via on the board. As i just killed some boards i would like to know if i can build a custom firmware which uses gpio2 as default tx pin? Using C i can use serial2 to commun...

I do not understand that too. As far as i found out you can set the dhcp hostname only if the esp had a connection to a wlan. But after a reconnect it won´t use it for a known wlan. You have to connect to another wlan and then back. My approach is, to first connect to an access point on my mobile, s...

Thanks for clarifying pythoncoder. Do you think it is a problem to always run the do_connect() in my code or is it better to first check if a connection could be "automatically" established?

Hmm ok strange thing, i flashed the pre compiled image back and testet the code again and it gave me the same error. I had to connect to my network first without changing hostname. After that the code did work again and changed the hostname. Can this be a bug or is it my fault?

Yes i did also try with a constant name, it is running fine on pre compiled 1.9.3 binary. But same code doesn´t work with self compiled code from master. I´m a bit unsure if the master has the same code as the pre compiled 1.9.3 version. On the mp download page you can only get the source of 1.9.2 f...

Hi, if i flash the 1.9.3 binary the following code runs flawless using the config(dhcp_hostname="hostname") from time import sleep_ms import machine from Config import Config Config1 = Config() def do_connect(): import network ap = network.WLAN(network.AP_IF) ap.active(False) wlan = network.WLAN(net...

Ok, i did some measurements and found out, that esp´s gpio2 is connected to the TX pin of the board. The U0TXD isn´t connected to any pins. and the U0RXD is connected to the RX Pin of the board.

Is there a way to get repl´s tx on gpio2 and leave rx on U0TXD ?

I love this little board and i also love micropython. But i can´t get them married :( I got a little progress. When i flash latest stable mp with nodemcu´s ESP8266Flasher.exe then my device will expose a wlan station named Micropython-99509e. But i can´t get a repl on com5. It works on all other boa...

Thank you for your replies. I didn´t make any progress too but i got managed to upload easyesp to the h801 so the board doesn´t seem to be defective. I tried to flash mp after i successfully flashed easyesp but there´s still the same behavior. espeasy comes with its own flash tool (esptool.exe) So i...
