Hi
I'm very glad to have an opportunity to help you with Arduino project.
This job is very appealing to me because I have a lot of experience in FW development and PCB design of various kinds of IoT projects using Raspberry Pi, ESP8266-12E, ESP32 WROOM and ESP32 WROVER module.
Yes, we can wifi sniffer with ESP8266 or ESP32. They're very powerful and cheap wifi+mcu.
Especially, I have previously done many ESP8266 & ESP32 projects with wifi feature.
I'll be very happy if I have a chance to show you my previous ESP8266 and ESP32.
I'm confident my skills and experience in ESP WiFi feature would make me a good candidate for your job.
I'd like to disucss the project in detail on interview.
Best regards.
Ivan
