I followed the OpenSignals_(r)evolution_Manual and have some issues to check my firmware.
I use "Plux Firmware Update Tool v1.2". After clicking the "Find Devices" button the MAC address appears.Then I click the "Check" button and receive this message:
The communication with the device was lost. Verify that the device is within range and turned on.
The device is within range and turned on.
I removed the device from my current Bluetooth adapter and reconnected it.
I don't use a third-party Bluetooth stack.
I already recorded ECG signals without any problems.
Thanks for your help and
