Thank you for the hint.
I have followed your advice and used the hcidump -X command. This is what I get:
< HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17
handle 37 voice setting 0x0060 ptype 0x003f
> HCI Event: Command Status (0x0f) plen 4
Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1
> HCI Event: Max Slots Change (0x1b) plen 3
handle 37 slots 1
> HCI Event: Synchronous Connect Complete (0x2c) plen 17
status 0x20 handle 37 bdaddr 00:0D:44:A5:8C:E2 type eSCO
Error: Unsupported LMP Parameter Value
> HCI Event: Max Slots Change (0x1b) plen 3
handle 37 slots 5
I must admit that I do not understand what this means. But I do
understand that there is an error:
" Error: Unsupported LMP Parameter Value"
Any ideas of what I could do next?
