As suggested in the manual on paper or online as pdf I tried to pair two SoudCore 2 speakers for stereo mode. A new one and an older one, which I updated with the 1904 firmware. They where bought on amazon.
Both speakers are starting the blue double flash after pressing the bluetooth button for a couple of seconds. Nothing happens after this.
When pressing the bluetooth button for a longer period (about 5 seconds) the speakers give a special jungle sound. The also doesn’t result in any coupling.
Can you help me?
