About a few days ago i buyed a new board on marked BLYNK V.1.4 20-08-11 that have some harware differences. Different (bigger) jst for battery, a new power led, and so on. The problem is that when i flash the same software on the new board nothing works. It seems that the at command response with echoed command. Example: I i send AT+GSN\r\n on the first board it response with

I solved by myself. There is a AT command to send to disable the command echoed in response. The command is ATE0

Thanks anyway
