SUPL Client with nRF9160 and improving battery life

pranav-ether

Hi,

I'm working on a GPS tracking application using nRF9160. The application is to send sensor data and location data every 15mins. I've build a prototype and I'm not happy with the GPS performance and power efficiency. GPS takes too long to get a fix so, I'm considering using SUPL client to improve fix time and accuracy. Once location works properly I'd like your help to improve battery life (I'm using a 1000mAh Li-ion battery).

I have applied for the SUPL Client licence and I have not received the download link yet.

Thanks

    Hello, 

    We would recommend using the nRF Cloud A-GNSS library. Have you looked at this? 

    I have applied for the SUPL Client licence and I have not received the download link yet.

    If you still want to use the SUPL client, please make sure that you have not opted out of receiving emails from us e.g. newsletter:

    And that you are following the information provided under the SUPL client:

    Kind regards,
    Øyvind

    I signed up for the newsletter and applied for the licence again now. How long does it take to approve the licence?

    I have looked into nRF Cloud's offerings and the plan is to use supl client for prototyping and nRF Cloud for production later. Will there be any major difference in performance of supl client (supl.google.com) and nRF Cloud's AGNSS?

    Are you using the same email as your DevZone account?

    Here are the key differences between SUPL (Secure User-Plane Location) and nRF Cloud A-GNSS (Assisted GNSS):
    1. Data Efficiency: The nRF Cloud A-GNSS library is more efficient to use compared to the SUPL library. It requires less memory on the device.
    2. Data Security: nRF Cloud A-GNSS uses encrypted data transmission, while SUPL uses a plain socket connection.
    3. Satellite Support: nRF Cloud A-GNSS supports assistance for both GPS and QZSS satellites, whereas SUPL is limited to GPS only.
    4. Licensing: No licenses are required from external vendors to use nRF Cloud A-GNSS. For commercial use of SUPL, you must obtain a license.
    5. Integration: The nRF Cloud A-GNSS library is highly integrated into Nordic Semiconductor's IoT cloud platform, making it easier to use within the Nordic ecosystem.
    6. Optimization: The A-GNSS solution available through nRF Cloud has been optimized for embedded devices to reduce protocol overhead and data usage, resulting in reduced data transfer time, power consumption, and data costs.
    It's worth noting that both SUPL and nRF Cloud A-GNSS serve the same primary purpose of providing assistance data to improve GNSS performance, particularly in reducing Time to First Fix (TTFF). However, nRF Cloud A-GNSS appears to offer several advantages in terms of efficiency, security, and integration within the Nordic Semiconductor ecosystem.

    Kind regards,
    Øyvind

    Yes, I'm using the same email ID for license signup & devzone.

    According to the admin for the download page they can see that you have applied and that your preferences were not update in the system. They ask if they can update this manually but needs to have confirmation from you due to GDPR. Do you accept that admin updates the data for you?
