Laird Connectivity is now EzurioBTM51x Series: BTM51x Simultaneous Profiles
On the Laird BTM51x, certain profiles can be used simultaneously (with restrictions) for various use cases. For example, A2DP (stereo audio) can be used at the same time as AVRCP (remote control) so that a Bluetooth speaker (audio sink) can control the music player (audio source) while streaming music.
The following are a few examples of simultaneous profile scenarios on the BTM51x.
1. A2DP, AVRCP, and SPP with one device
Note: A2DP is the Advanced Audio Distribution Profile. AVRCP is the Audio / Video Remote Control Profile. SPP is the Serial Port Profile.
2. A2DP, AVRCP, and SPP with two devices (any combination is possible)
3. A2DP, AVRCP, and SPP with three devices
