ESP-12 external powered
Posted: Mon Feb 27, 2017 11:44 pm
Hello,
I would like to connect a ESP-12 on my otgw, due to limitations and possibilities to get get a cable from boiler to raspberry pi with domoticz.
I have the usb otgw and moved to another house.
Though I dont want to solder new components, Im not so good in that.
I can power the ESP-12 external, but no signals coming trough from otgw. If I using a TTL cable, in OTmonitor I see correct values.
If I connect the ESP-12 external and only connect RX to TX and TX to RX, I dont get any values. It does connect via OTmonitor / port 23 but no values in the log.
Is that because I dont use the ground pin from the otgw?
If so, can I connect the ground from the external psu (phone charger with modified usb cable to pin cables) to the ground of of the otgw and also connect to the esp-12 module? Or should I use somehow the gpio ground pin ?
