Any more details on the 1.9.2 setsockopt(IP_ADD_MEMBERSHIP) update?

Have been looking now but haven't found any more details on setting up the esp to join a multicast group/designate a multicast IP address to send/listen to. Was curious if this functionality is actually available now?

Re: MPU9250 I2C problem

I've actually had exactly the same issue (though don't know how to fix it, sorry). I can scan() my PFC8574 port expander (so I know I2C is working) but it doesn't pick up the sensor (or, for that matter, a few other items). Any recommendations are welcome.

Re: Avoid flash wearing by altering behavior originally introduced by Espressif (the inventor of the ESP8266)

For the records: 50 hours into discussion and 19 vs 0 votes in favor of the PR. Yay, only 981 to go, good luck. I would have thought a change should be made unless 500-1000 people vote against it, not the other way round. It's not like everything else wasn't implemented from scratch and we consulte...

Re: Avoid flash wearing by altering behavior originally introduced by Espressif (the inventor of the ESP8266)

Just finished reading through all pages of this post and am left with a question: given there's no technical reason against it, was there anything wrong with the compromise solution proposed? If I read all this correctly, the suggestion was implementing a save_config() with an optional boolean to al...

Re: Issue with ESPs talking to each other over UDP socket

Alrighty, finished testing. The big issue was indeed my devices both having 192.168.4.x as their AP lan. Guessing it was messing up the child more. Now have TCP and UDP working without incident after reconfiguring the child's network to a different IP range (192.168.5.x). Thank you again

Re: Issue with ESPs talking to each other over UDP socket

Sorry for the late reply (busy week) Thank you chrisgp, I'm definitely thinking I muddled the binding (which I didn't even document in the initial post, probably because I didn't have it straight). Have done that properly and it's now working properly. Or at least with UDP. Still have more testing t...

Re: Issue with ESPs talking to each other over UDP socket

Just tried TCP and it seems to suffer even worse. While it can establish a connection in either direction (either side can be listener and the other can be the client), it cannot send a message either up or down regardless of which is which.

Re: Issue with ESPs talking to each other over UDP socket

Oh, and as a followup, there's no way to do a broadcast packet with UDP to the whole local wireless network is there?

Issue with ESPs talking to each other over UDP socket (solved)

Hello again, Am currently experimenting with ESPs in a kind of tree topology network (where each ESP is both a client and an AP). As an early proof-of-concept I was trying to get them to talk to one another using simple UDP sockets. Unfortunately I've hit something of a snag and was wondering if it'...

slightly odd behaviour with WLAN.config()?

Breaking into 1.8.4 (been a while since I've had time to build anything) I've noticed some strange behaviour with the network library. Specifically I'm having trouble changing the essid of the AP wifi on my little wemos d1 mini. I've tested this in both the REPL and webREPL and have had odd results....
