As known to us, the fifth-generation Bluetooth chip BC-05 is a single-chip solution produced by CSR, supports Bluetooth v2.1+EDR, with long working range and including HSP/HFP, A2DP, AVRCP, OPP, DUN, SPP, profiles.

With the progress of the times and the diversification of applications, many projects have also put forward higher demand for the functions of Bluetooth chip, e.g. more and more projects need to apply Bluetooth LE. Feasycom has developed some modules that would be better alternatives for BC-05 being out of production. Hereby we recommend 2 models.

1. FSC-BT909 | Class 1 Bluetooth 4.2 Audio Transmitter Dual Mode Module

It is a Bluetooth Dual-Mode Module with Bluetooth V4.2 audio + data specifications ( Supports BR/EDR & LE) based on CSR8811.

FSC-BT909 is a Class I solution, the working range for data transmission can get up to 300 meters. With an external antenna the distance could be extended. FSC-BT909 supports data and audio transmitting (receiving) simultaneously. In addition, there is a firmware for multiple connections, it can be as a transmitter to connect with two audio receivers at the same time.
