I need to broadcast custom became advertising data from an iOS / Android device to many custom BLE devices. My goal is to set bytes from was the adv package to broadcast it to nearby ble units.
As far as I know, I need to set the payload to the ad package on the ios / android device.
My case, it is not possible to just connect to all ble devices and write characteristic values because I need to broadcast data to many devices.
Is there any way to solve this problem with fluttering / fluttering blue?
