2026 年 07 月 01 日2026 年 07 月 06 日由Raytac Corporation撰寫發表留言

[CA, USA/Taipei, Taiwan]

Raytac Group, a worldwide leader in wireless modules, wireless solutions, and a Nordic-recommended third-party module manufacturer, is pleased to announce the official release of the AN54LQ-AT and AN54LV-AT series, our newest Bluetooth® Low Energy AT Command modules built upon Nordic Semiconductor’s nRF54L15 ultra-low-power wireless SoC.

Designed for engineers who want to integrate BLE quickly and easily, the AT Command series comes with pre-loaded peripheral (slave) role firmware, enabling straightforward UART communication with a host MCU through simple AT Commands.
Built on Nordic’s next-generation nRF54L15 SoC, the series delivers exceptional power efficiency, reducing power consumption by approximately 50% compared to previous-generation nRF52-based AT Command modules.

The nRF54L15 AT Command family is available in five variants to satisfy different RF and mechanical requirements.

AN54LQ Series
– Ceramic chip antenna: AN54LQ-AT (Click here for full product details)
– PCB trace antenna: AN54LQ-PAT (Click here for full product details)
– u.FL connector for external antenna: AN54LQ-UAT (Click here for full product details)

AN54LV Series
– Ceramic chip antenna: AN54LV-AT (Click here for full product details)
– PCB trace antenna: AN54LV-PAT (Click here for full product details)

AT Command Development Kit
– AN54LQ Series: AN54LQ-AT-UART-S (Click here for full product details)
– AN54LV Series AN54LV-AT-UART-S (Click here for full product details)

The standard AN54LQ family measures only 9.5 × 13.7 × 1.8 mm, while the AN54LV family further reduces the footprint to just 6.4 × 8.4 × 1.5 mm, making it an excellent choice for wearable devices, portable products, industrial sensors, medical devices, and other space-constrained applications.

Engineers can integrate Bluetooth communication(peripheral role) into an existing MCU platform without implementing the Bluetooth LE protocol or maintaining a Bluetooth LE firmware stack.

Acting as a seamless bridge between the host MCU and Bluetooth devices, the AT Command module enables easy wireless communication without any complexity of firmware development.

Why Does Raytac AT-Command Module Not Require An End Code Mechanism?

2024 年 04 月 25 日2024 年 07 月 03 日由mandyraytaccom撰寫發表留言

Developers may be familiar with using ‘\n’ (hex 0x0A) or ‘\r’ (hex 0x0D) as end codes to determine the end of a data packet when writing programs. In the original Nordic SDK example code, ble_app_uart, is to consider the reception of 244 bytes or the presence of ‘\n’ (hex 0x0A) or ‘\r’ (hex 0x0D) as end code as the end of a data packet. The program then sends this received data via BLE to APP.

Developers encountering Raytac AT-Command module for the first time may find it very unfamiliar and be puzzled by the absence of 0x0A or 0x0D end code. You may raise questions about how to receive complete information without relying on these end code? Therefore, we’ll provide explanations for common use cases of AT-Command in both connected and disconnected scenarios:

In the connected condition –

Raytac’s AT-Command module operates in Pass-Through mode. For instance, when the APP sends 0x41 0x42 0x43 (3 bytes) through the module to the MCU, the MCU will receive only 0x41 0x42 0x43 (3 bytes). When APP sends these 3 bytes, there is no need to include the 0x0D end code or 0x0A end code at the end. The same approach applies when the direction of transmission is reversed (i.e., when the MCU sends to the module and then to the APP).

Here, it’s crucial to note that there is a specific consideration for the “Data Interval" (DI) setting between transmitting one data packet and the next. Failure to configure the DI appropriately may result in packet loss and lead to Bluetooth disconnection shortly after data transmission. The recommended DI values vary at different Baud rates, and you can refer to the AT-Command specification for suggested DI values.

As an example, consider Raytac AT-Command module in the scenario of “Mobile App -> Module (MDBT42V-AT) -> MCU," with a Baud rate of 9600, no flow control, and a data length of 244 bytes. In this case, the DI value for transmitting data must be at least 250ms to prevent packet loss.

In the unconnected condition –

Providing explanations to the Bluetooth module by sending AT commands from the MCU (or Console) is illustrated below. There is no need for 0D or 0A end codes at the end.
