Under normal circumstances, when we are developing a Bluetooth audio product, we often not only require the Bluetooth module to support A2DP Sink or Source, but also require the module to support data transmission, for data transmission, the SPP and GATT profiles are most commonly used.

So which module supports SPP Master & A2DP Sink at the same time?

1. FSC-BT802：CSR8670 chipset, Bluetooth 5.0 dual mode, supports A2DP (Source & Sink), SPP, GATT, PBAP, HFP, HSP, AVRCP, HID protocols, small size: 9.7mm x 11.5mm x 1.8mm, already certified by FCC, CE, BQB, TELEC, IC, KC.

2. FSC-BT966: Cypress CYW20706, Bluetooth 5.0 dual mode, supports A2DP (Source & Sink), SPP, GATT, PBAP, HFP, AVRCP, HID protocols.

3. FSC-BT909: CSR8811, Bluetooth 4.2 dual mode, Class 1 long range Bluetooth module, supports A2DP (Source & Sink), SPP, GATT, PBAP, HFP, HSP, AVRCP, HID protocols, already certified by FCC, CE.

4. FSC-BT806B: CSR8675, Bluetooth 5.0 dual mode, high performance Bluetooth audio module, supports A2DP (Source & Sink), SPP, GATT, PBAP, HFP, HSP, AVRCP, HID protocols, already certified by FCC, CE, BQB, TELEC, IC, RCM.

There must have one model suitable for the customer, we also have many cost-effective Bluetooth modules support SPP slave & A2DP sink, such as FSC-BT1006A (adopting QCC3007) Bluetooth 5.0 audio module, this module supports TWS feature as well, if there any audio project related the Bluetooth module, don’t hesitate contact us.
