Everybody use linux + nano editor + command line for uploading as I do ? :) so, I share own method add to the ~/bashrc EOF string source ~/esp_upload.sh Hint: dont forget logout/logit to take effect esp_upload.sh #!/bin/bash #VladVons, 2021.01.25 #add to ~/bashrc EOF source ~/esp_upload.sh and logou...

docker mentioned in official documentation. sudo docker run --rm -v $HOME:$HOME -u $UID -w $PWD larsks/esp-open-sdk docker: Error response from daemon: No command specified. so i went your path using git I also visited your project pysmartnode and found there a script for esp32 firmware compilation....

Tell me please what IDE you use for ESP32 micro python developing ?
Thony, uPyCraft, PyCharm or VSCode + some plugin or something else.

Is it possible to debug python source code at all ?

While looking for esp-open-sdk compilation issue i installed many packages which caused invalid custom firmware.
I reinstalled Ubuntu and now everything is ok.

Note: To avoid many errors don't use python virtualenv.

Thanks kevinkk525 once more !

Thanks for script.

Finally, after long compilation i have got a hand made firmware-combined.bin (641276K)
But it doesnt work.
No python prompt. Only garbage in terminal.

to speed up WiFi connection router should receive from ESP:
static IP, bssid, channel number

1) How to get from successful WiFi connection following data?
- channel number
- bssid

2) How to connect WiFi with certain channel number?
connect() has no such parameter

loading micropython kernel and init own classes 1.7 seconds WiFi Connection With no parameters (previous ESP ROM data): 3.5 seconds for connect With static IP address + 'bssid' parameter: 2.5 seconds for connect In post above from 'tve' pointed about 0.175 sec with ssid, passwd, channel, bssid, ip,...

I try to use ESP8266 with independent aku power supply, so mimimizing power consumption is important. DeepSleep uses 0,2 mA Wake up and WiFi activity uses 70-150 mA for a 3-6 seconds to connect to a router. Is it possible to reduce WiFi negotiation time? I think assign static IP address would be a s...
