ESP32 Forum

hello everyone
i use purchased pre tested code from game company
it has connection between the controller and the game with bluetooth esp32 to esp32
after installing every thing good it worked good but i keep loosing the bluetooth connection randomly
and sometimes when the controller starts to move away from the game less than 1 m distance
i tested everything and don't know where's the problem
that's the esp that i use

that video show the problem

https://youtu.be/ujJEWMZREUw?t=71
is that even normal or there's problem in the esp
or there's somthing i need to check
although the code is sold many times from that company and supposed to work better
best regards

The position and orientation of the Bluetooth antennas can affect the signal strength and range. Ensure that the antennas on both ESP32 modules are positioned properly and are not obstructed by any objects that may interfere with the signal. Try different orientations or consider using external antennas for better signal reception.

Bluetooth operates in the 2.4 GHz frequency band, which is shared with other devices like Wi-Fi routers, microwave ovens, and cordless phones. Interference from these devices can disrupt the Bluetooth connection. Try moving the ESP32 modules away from potential sources of interference or switch to a less crowded Wi-Fi channel if possible.
