Hello everyone, I have customised the following program which connects via bluetooth and downloads data (download result below). Unfortunately I don't know how to download data from two devices simultaneously via ESP32. Now only after changing in to I connect to the second device. Please help. . .

Familiarise yourself with the mesh library only it is not BT, but Wi-Fi transmission (works smoothly) the number of devices is arbitrary

. Yes via WiFi without any problem, but the meters they connect to can only communicate via BT.
