The ESP was powered with it’s own power supply. I tried tying the resets together but it has the same behavior.
I’ll try to understand why… if you have any other suggestion please let me know.
Thanks for your help.
Otherwise I do not know. I run a Mega/ESP-01 combo and they both power up together.
Powering the ESP-01 first, then the Mega works fine.
But if I power the Mega first, then obviously it gives the error as the ESP-01 is not powered, as is needed in order to respond But I have a auto re-connection routine that handles that anyhow and thus it will work as soon as the ESP-01 is powered up.
Hi,
I think it’s a hardware problem. When I power everything the voltage between RX and GND is 2 Volt?
I don’t know why and I’m struggling to understand why. If u have any idea please let me know.
I’m going to try with another esp01 and see if it’s somehow dameged.
Thanks
Paul
