booting flashed esp01 (1 MB)
Posted: Tue Mar 30, 2021 1:42 amI flashed Tasmota 9.3 , and with NO LOAD on GPIO 0 ; the booting is OK.
Since I want to drive a relay on GPIO 0 , I connected NPN with 1k to GPIO 0 . The ESP01 failed to boot
Removing the NPN it boots with no problem.
The funny thing is; if I connect the NPN AFTER booting the relay WORKS !!!!!!!
The wiring is very simple (ESP01 VCC 3.3, Ground, CH connected to VCC , TX,RX,Reset are floating)
Any help will be appreciated
