Hi,
When I compare ESP-WROOM-32 datasheet with ESP-WROOM-02 datasheet, the specs looks almost identical: average current consumption 80 mA, sensitivity -91dBm @ 11 Mbps. But when I test real modules, their performance differs drastically. Running Arduino WiFiScan sketch on ESP-WROOM-32 and on ESP-12F, I can see the following:
- ESP32 module consumes about 120 mA, ESP8266 module consumes less than 70 mA
- ESP32 module can see 5...10 WiFi networks, ESP8266 module can see 14...18 WiFi networks.
It looks like ESP32 module performance is significantly worse than ESP8266. Why?
Regards

Re: ESP-WROOM-32 specifications
There are several sketches named WiFiScan: for WiFi shield, for ESP8266 and for ESP32. I should upload the sketch for ESP32.after uploading sketch in serial monitor I see ascii character ??
Re: ESP-WROOM-32 specifications
I've experienced the same issue. This is kind of buggies should be fixed. make sure you use 115200 (stock setting) Baud for serial monitor ("make menuconfig")sentu19 wrote:i having problem with ESP32 after uploading sketch in serial monitor I see ascii character ??

Re: ESP-WROOM-32 specifications
Reapeating the same question:
Why ESP-32 consumes 120 mA average? It should consume 80 mA as per documentation. I have checked several development boards, all consume more than promised. All ESP-32 are quite warm.
