Hello,
We only support a handful of RFCOMM Bluetooth services. If you are trying to access a service not on this list you will see the error that you are reporting (0x8007277c).
The following RFCOMM services are supported via the name value:
- name:serialPort
- name:obexObjectPush
- name:obexFileTransfer
- name:phoneBookAccessPce
- name:phoneBookAccessPse
- name:genericFileTransfer
