@lupyuen I used the ESP boards and thought they were okay. After the BL602 learning curve, I see two different products with two different purposes.

@lupyuen The ESP32 is the evolution of the ESP8266. The 82 was designed for serial to wifi communication. Both the 32 and 82 do this very well. The reason why it ended up in IoT was likely due to it being so cheap but reliable. I liked your take on the differences between the two.

@lupyuen *better performance on paper.

The ESP32 was only able to be detected in a very small area (<10m) while the BL602 was able to be detected up to approximately 20-30 meters in this test.

@lupyuen I will share the results. It was a means to verify the documentation of both modules. I put a BL602 in a closed room with small windows and concrete walls. The ESP32 was placed outside the room in an open area surrounded on three sides with concrete walls, one of which had a window. The two boards were used in BLE Mesh Node configuration (guess what I tried to test). So I used a smartphone and walked down both hallways continuously scanning for BLE devices. The BL602 has a BLE performance (on paper.)

@lupyuen I ran some basic tests on the BL602 and the ESP32. It's like comparing a weird WNIC to a device that was clearly designed to retrofit machinery and then upgraded.
