Re: RX/TX socket buffer sizes for ESP32?

Some test results: I can create 8 different sockets. After this I will get an OSError21. For UDP-sockets: each UDP-socket can buffer up to 6 UDP-packets with 1472 bytes (MTU = 1500 bytes). If there are more than 1472 bytes of data in the UDP-packet, the packet will get lost. Every UDP-packet after 6...

Re: How to delete a static IP?

On the WiPy it is possible to use sta.ifconfig(config="dhcp")? http://docs.micropython.org/en/latest/wipy/library/network.html?highlight=timeout#network.wlan.ifconfig But on the ESP8266? Doing a reset will be a solution - it works for this but I guess but it is not the best solution. import machine ...

How to delete a static IP?

Hi, I want to connect my ESP8266 to two different APs... on the first AP, the ESP8266 should have a static IP, but on the other AP it should be non-static. But after the connection to the first AP with a static IP, and doing sta.disconnect() #from the first AP sta.connect(<ESSID second AP>,<password...

ESP32 - unable to receive multicast if ESP32 is access point

First, my MCAST-sender-receiver code: #MCAST_ADDR = "239.255.255.250" MCAST_PORT = 9898 sock = socket.socket(socket.AF_INET,socket.SOCK_DGRAM) sock.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1) addr = socket.getaddrinfo("0.0.0.0",MCAST_PORT)[0][-1] sock.bind(addr) opt = bytes([239,255,255,250]...

How to combine bootloader.bin, partitions.bin and application.bin?

Hi there, to build a firmware for the ESP8266 I use this one: https://github.com/adafruit/esp8266-micropython-vagrant Like you can see in the README, the result will be an output "firmware-combined.bin". But for the ESP32 there are build three binary firmware images (bootloader.bin, partitions.bin a...

How to receive more than one UDP-packet on a single socket?

With an UDP-Socket a server can receive a UDP-packet during "doing some stuff", and later read the packet from socket.recv(). For example: >>> import network >>> import socket >>> ap_if = network.WLAN(network.AP_IF) >>> ap_if.active(True) >>> s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM) >>> s...

Re: WLAN.config(hidden="False") didnt work

Found the solution: You can set WLAN.config(hidden= "True" ) or WLAN.config(hidden= True ) - both works. But you have to use WLAN.config(hidden= False ) to reverse this... WLAN.config(hidden= "False" ) didnt work. Inserting the boolean False as a string didnt work, just for setting it "True". And co...
