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.
Raytac AT Command Family
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.
Central Role AT Command Module: MDBT42Q-ATM
Central Role AT Command Module: MDBT42Q-PATM
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.
