Strange behavior in Sonoff basic R2 (solved)

[msillano]

hi Martin, hru?
I'm working on a new project, that helps now.

Of course, using Sonoff & esp_mqtt . But I get strange behavior:
n,b, using "Sonoff RF R2 POWER V1.0 " aka sonoff basic R2

1. flashing with esptool: OK
2. Serial connection to complete the config via the same FTDI + putty :
   I get a loop with garbage on terminal:

It is a pause after 'on port 7777'.

I used also an old bin version: same. Until now I used Sonoff TH_V1.0 without any problem.

p.s.
Before to send to you I done one more tentative, using esptool with erase_flash before.
Worked !! I get the prompt !

I send you same, maybe this is a piece of useful information to put in README
Best regards
