The Leader in Embedded Bluetooth

What makes dotstack so special?

SEARAN’s ultra small and flexible Bluetooth stack, dotstack™, was designed for low cost and low power embedded devices. Bluetooth SIG compliant, well tested and consistently certified, dotstack™ has the smallest footprint, easy to port and runs on most popular platforms and RTOS. dotstack™ has the lowest latency and highest data throughput in the industry.

V2.1 + EDR, V4.0, V4.1, V4.2 and 5.0. dotstack™ can be used as a single or dual mode stack, and has all necessary protocols and profiles for BR/EDR and/or BLE(GATT). V5.1 with direction finding (AoA, AoD) developed and tested, and pending certification. V5.2 for LE audio in development.

Minimum requirement – 5.6KB RAM and 57KB Flash that includes RTOS and a sample application for SPP or BLE(GATT).

Tested with Bluetooth chipsets from CSR, Texas Instruments, Toshiba, Intel, Marvell, Broadcom, Realtek, RDA.

Tested with PHY and LL from Synopsys.

Tested for Interoperability with Microsoft, Toshiba, Widcomm/Broadcom, MAC OS X, BlueZ and other stacks used in mobile devices.
