Frequently Asked Questions

What development tools and SDKs are recommended for programming the Holyiot 21069 module?

Developers typically use Nordic Semiconductor Semiconductor's nRF Connect SDK, which is based on Zephyr RTOS. This SDK provides full support for the nRF5340's dual cores, all wireless protocols (Bluetooth LE, Zigbee, Thread), and security features. Programming and debugging are done via a compatible SWD/JTAG probe like the Segger Segger. The module can also be integrated into IDEs like VS Code with the nRF Connect extension for a streamlined workflow.

How do I configure the module for Bluetooth Long Range or LE Audio applications?

Within the nRF Connect SDK, you select the appropriate Bluetooth LE feature set during project configuration. For Long Range (Coded PHY), enable the corresponding options in the Bluetooth stack to extend range at the cost of lower data rates. For LE Audio, utilize the Audio Developer Studio and the Broadcast Audio Source (BASS) or Capabilities Exchange Service (CAS) profiles defined in the SDK. Firmware must be built targeting the application core while the network core handles the RF protocol.

What is the typical power consumption in different operational modes (TX, RX, sleep)?

Referencing the nRF5340 datasheet, current consumption varies by mode and clock speed. Peak current during radio transmission at +3 dBm is approximately 5.3 mA. In active mode with the application core running, expect currents in the low mA range. The module supports multiple low-power sleep modes; in System OFF mode with RAM retention, consumption can drop to sub-μA levels, which is critical for battery-operated wearable and sensor node designs.
