#52734 Hi, red_car.

After almost an year, I could take back this project again!
Well, today I updated ESP-01 firmware to 0.22 version and... bingo! The problem was finally solved.

Fernando Gauenzi, only today I found your post, so I didn´t tested it, but I´ll try this with one of modules with version 0.21 I own.

Thanks to all for contributions!
