Bluetooth® audio is enabled by default in Ref-OS-IoT, there is no need to install any additional software. To play audio on a Bluetooth® headset or speaker, enable Bluetooth® and scan and pair to the speaker device.
If the device is not connected, issue:
The Intel® Joule™ platform offers multiple solutions for data retention: eMMC, SD Card, and SDIO. Each storage type is intended for a specific use but offers the developer the flexibility to choose between them.
The module contains an embedded MultiMedia Card (eMMC) with ether 8GB or 16GB of storage capacity. See the System on Module Overview for module configurations.
The following recommendations outline the elements of a robust and electrically stable module mounting method:
The I2S_1 port on J6 is available for audio playback and recording, for example through an audio codec. It can operate in I2S and PCM master or slave modes. The signals are shown below.
The expansion board contains three buttons. Two of the three buttons have predefined operation, while the third button is user defined. The three buttons are titled:
The HDMI subsystem provides a micro-HDMI* Type-D connector at J10 for connecting compliant displays and HDMI audio devices to the development platform. Refer to Expansion Board Interfaces for the location of the HDMI connector.
The Intel® Joule™ expansion board provides the required filtering and voltage level translation (shifting) between the module HDMI bus and the physical interface outputs.
You have several options for cooling the Intel® Joule™ module based on the amount of work the module is doing.
The module thermal plate can dissipate workloads of less than 2 watts. A fan moving air across the thermal plate is recommended when not using a heatsink. See Reference Fan Mounting Block for a fan mounting plate that you can 3D print yourself from the included files. We recommend the Sunon* fan, Model# MC30100V2-000U-A99 fan or equivalent.
There are several potential causes for this issue:
