Raytac announces release of AN54H20 Series Module based on Nordic’s nRF54H20 chip solution

發表於 由撰寫發表留言

Raytac Corporation, a Nordic-recommended third-party module manufacturer based in Taiwan, today announces the upcoming release of the AN54H20 modules, which are built on the base of Nordic’s nRF54H20 SoC.

The AN54H20 module comes in a 9.8 x 13.8 x 1.8mm (0.37 by 0.53 by 0.07 inches) dimension factor and offers 3 versions of high-performance antennas, including ceramic chip antenna, PCB-mounted antenna, and uFL connector for external antenna. Output power is adjustable up to +10 dBm and data rate is adjustable up to 4Mbps to maximize RF performance.

Powered by multiple processors, AN54H20 modules provide the IoT field with access to a whole set of improved features, including 2MB flash memory/1MB RAM and bigger processing power for more complicated computations.  It also enhances protection against security threats, providing developers with protection while building technologically advanced IoT applications.

Hardware wise, AN54H20 inherits nRF54H20’s set of versatile, advanced, and low-power peripherals alongside DMA support, including high-speed USB, CAN-FD controller, 14-bit ADC, 2 x I3C and plenty more.  What’s more revolutionary is that AN54H20 brings power efficiency to a whole new level through accurately controlling currency consumptions under various modes, allowing smaller batteries to be implemented in the applications while increasing its life expectancy.

“We see the AN54H20 series as a potential market changer.  The compact size gives developers a seamless switch from the previous generation modules to AN54H20, and the remarkable power efficiency and characteristics AN54H20 brings will offer a magnificent effect to the inescapable hot trend of IoT and other various industries." – Lyon Liu, President of Raytac Corporation.

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

發表於 由撰寫發表留言

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.
