AT command module, an easy solution provides developers a quick breakthrough to Bluetooth connection. Without firmware effort needed, simply have commands setting on MCU and the start to enjoy the implement of bridging connectivity between devices through Bluetooth.
After Raytac’s Peripheral (Salve) role AT command module released, the demand of Central role has been highlighted by developers.
To have a completed solution, Raytac today announced Central role, as known as Master, AT command module released.
Differ from Peripheral role AT command module built by nRF52810 solution, Central role AT command module deployed Nordic nRF52832 which employees 64K RAM and 512K Flash Memory.
The AT command modules, same as Raytac’s all other lines, are Bluetooth qualified (BT5/BT4.2) and FCC/IC/Telec/KC/SRRC/NCC pre-certified and CE compliant. A completed hardware and preloaded AT Command firmware solution not only simplify the designs and reduce BOM cost, but also waive the cost of regulatory burden and speed up time to market efficiency.

Bluetooth SIG announced the deprecation and withdrawal of older versions of the Bluetooth Core Specification.
Bluetooth SIG has policy in place to introduce the deprecation and withdraw process for older testing specification, listing procedure and core specification.
For core specification placed into withdrawn status, it will not be allowed to use the withdrawn version anymore. Any product wishes to qualify the Bluetooth Design under this deprecated version must pay additional deprecation fee.
Please refer to the revised plan and schedule summarized as below,
1.Withdrawal of the following on January 1, 2019:
Bluetooth Specification Version 2.0 + EDR
2.Deprecation of the following on January 1, 2019 and withdrawal on July 1, 2020:
Bluetooth Specification Version 2.1 + EDR
Bluetooth Core Specification Addendum 1
Bluetooth Specification Version 3.0 + HS
Bluetooth Specification Version 4.0
Bluetooth Core Specification Addendum 2
Bluetooth Core Specification Addendum 3 revision 2
Bluetooth Core Specification Addendum 4
Bluetooth Specification Version 4.1
