That is weird, it looks like somehow it is showing up as two different hotspots. More confident, the replacement will fix it.
Yeah, thatâs one of the things that I noted earlier in the thread, but that doesnât happen every time. It happened more frequently in the cold room, but even there not every time. I gave it a quick google when it initially happened but didnât find anything
Well, as an update it doesnât seem to be the ESP. No changes from what I can see
Do you have a way to âBenchâ power the ESP01?
With a programmer or even with jumper leads and a 3.3V power supply?
If not, can you monitor your host boardâs 3.3V with a DMM while the board is plugged into it?
I donât have one unfortunately, I just started doing anything with electronics last year. I used a digital multimeter earlier while it was running to confirm 3.3V. Iâll try again tomorrow with the new board chip though and report back.
Well shoot. Tuesday or Wednesday I will have to ship out a board, power supply, and esp. Weâll swap and I can dig into that some more.
Sounds good, Iâm going to talk to the departments electronics guy on Wednesday to see if he has any ideas
Sorry for the delay, everything is tested and on its way for a swap!
All good, thanks for all the help!
Hi @Ryan,
Iâm also having a problem with my ESP-01s not showing up.
In my case the blue light either stays on all the time (see picture below), or doesnât come on at all.
Iâm just going to order a programmer + new ESP-01s from aliexpress and flash it myself.
Can you point me to the instructions on how to flash it for use with the SKR 1.2?
Thanks,
Bernard
Those two links should get you going to flash it.
Any espâs that have left here since the original post have been tested twice. I have not found any issues. And for whatever reason the stuff that came back worked fine as well.
The programmer and new esp01s arrived from aliexpress. Got it up and running within 5 minutes following Add Wifi to SKR Pro step by step
I used esptool.py from the extra/esptool package on Arch Linux to do the firmware flash. (esptool.py -p /dev/ttyUSB1 write_flash 0x00000 firmware.bin
)
I havenât connected it to the cnc yet though, I wonât have time to do so until somewhere next week.
[EDIT]
I just tried to flash the original esp01s I had, and it seems to be dead, the esptool canât connect to it. But that could very well be my own fault, I gave it 5V when trying to get it running before (after it wouldnât show me a SSID on 3.3V).
