Blynk NCP arduino uno + esp01

Hi, I’m using Arduino Uno + esp01 with its adapter .
I uploaded the bin file to esp01 ( bin BlynkNCP_generic_esp8266_1M.flash.bin )
I can communicate with blynk, I can change the wifi credentials by pressing reconfigure on the blynk iot app, but I can’t send firmware via OTA.
Can someone help me ?
