Q: How do I query the sdk version provided by Thundercomm? What is the update policy provided by Thundercomm when Qualcomm's baseline is updated? In particular, how will Thundercomm support updates if Qualcomm has updates due to security vulnerabilities or other reasons?
A: Please refer to our SDK Release Note document for the SDK version. When Qualcomm's baseline is updated, Thundercomm will also synchronize the update. The update frequency will vary according to the current stage of the product. For details, contact our technical support personnel.
Q: Do you have mature OTA proposals? Or, do users need to develop on their own?
A: The SDK released by Thundercomm contains the firmware upgrade scheme on the device side. The OTA scheme completed by Cloud + device needs to be developed by customers themselves; alternatively, users can purchase our FOTA scheme. For details, please contact our technical support personnel.
Q: As to OTA, if we use our own Cloud, does your company have a mature open-source solution? Or, is your solution the only choice?
A: Thundercomm provides firmware upgrade schemes and API interfaces on the device side. Customers can develop FOTA schemes by themselves according to API interfaces, or purchase FOTA schemes from Thundercomm. We also offer FOTA customized service, please contact our technical support personnel, or submit work orders on our technical support system (https://support.thundercomm.com).
Q: Can you provide technical support to solve the problem of file system tailoring and necessary library dependence?
A: Thundercomm has dedicated FAE team and R & D team to provide technical support to customers. You can contact our technical support staff for technical support. Users who have created projects on our technical support system (https://support.thundercomm.com) could directly submit work orders on the system.
Q: Is there any explanation about the openness of the SDK provided by your company (including the openness of 4G, Wi-Fi/BT, camera, IMU, audio and other modules)? For example, in addition to the open kernel, is source code of SensorSerivce also open?
A: For the extent to which the code is open, please refer to Release Note of relevant SDK.
Q: Is there a GPIO resource table for the module available?
A: The relevant content is in the module datasheet released by Thundercomm. For details, please refer to the corresponding module datasheet document.
Q: Is there a recommended list of cameras? Are cameras excluded in the recommended list also supported?
A: Supported camera modules will be explained in the DK (Development Kit) documentation provided by Thundercomm. As to whether cameras excluded in the recommended list are supported, users need to confirm the camera spec by contacting our technical support staff, or submitting work orders on our technical support system (https://support.thundercomm.com). As Thundercomm opens the code of camera driver part, users can develop camera driver by themselves, and Thundercomm can provide technical support. We can also provide camera related customization development; for details, please contact our technical support personnel.
Q: Do you have production tools for mass production, such as burn-in tool, test tool, factory mode, etc.?
A: Thundercomm provides production line tools for SOM mass production. However, customer product-oriented production tests need to be customized according to customer needs; in addition, tool customization is not for free.
Q: As to production tool, can your company provide users with source code for the existing test tools, so that users can do customized development on this basis?
A: Some test tools include Thundercomm's own software tools and we do not offer source code of this part. We will provide API invocation interfaces for users to modify themselves; also, we can provide technical support. For more information on customization of production tools, please contact our technical support personnel, or submit work orders on our technical support system (https://support.thundercomm.com).
