- Mon Mar 02, 2015 6:34 pm #11130 Anyone besides myself having troubles which seem to be related to rf feedback or interference?
I have one breadboard setup with an -12 chip which works reliably every time. But another bb with -01 chips is just flakey all the time.
I finally determined that the orientation of the bb, the power wires, the USB-serial wires, and holding my mouth just so makes the difference between success and failure.
Also, I have an Amazon Echo sitting about 10" from my bb setup - it sometimes goes offline from my network at the times the -01 is accessing wifi!
If anyone has any tips to tame this rf please let me know. I'm using bypass caps, and have found that replacing long loopy DuPont cables on the bb with short solid wires, and cutting leads on LEDs & resistors seems to help.

I was planning to use some esp-12 modules for switching 220 volt loads but i'm not manage to get a stable environment.
Wires leading to the load ( close to the module ) wil cause a reset when switching the load on ( 1 out of 50 times ).
When i use the setup with no load it works fine ( i tested for 1 day ).
Touching the module sometimes leads to a reset.
Wifi activity sometimes leads to a reset.

I tried 2 different modules one of them with a development board for that module and also several
powersupplies including a litium ion accu.
All with the same result as soon as i start switching loads.

If i can't get this fixed i wil have to go back to the NRF modules.

- Wed Mar 04, 2015 4:59 pm #11317 The ESP-12 modules are shielded, though. I have no problems with over-the-air TV reception with an ESP-01 (it's unshielded).

Have you tried an isolated power supply? (Batteries.)
