VMA 205 espcomm_upload_mem failed


#1

Hi,

I’m having difficulties with setting up VMA 205 WiFi ESP-WROOM-02 SHIELD. I have connected everything as mentioned in User manual but when I’m trying to flash example code I get following error message:

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

Everything is connected like this:

Can somebody please help me resolve this issue? I’ve tried some tips from this topic: VMA101 with a VMA205 - warning: espcomm_sync failed but I am not willing to spend more money for VMA 440 specially because VMA 205 should be plug and play…

I tried tips from mentioned post but without VMA 440 - So I need to have VMA 440 in order to use VMA 250? Is there any other solution besides VMA 440?
