Remember that Qualcomm does not offer support or drivers to end consumers. Qualcomm sells Integrated Circuits (IC’s) to module manufacturers or other Original Equipment Manufacturers (OEM’s) and under contractual obligations cannot offer end user support. If there are issues regarding configuration and usage of your product, please contact the OEM’s technical support department.

Our suggestion is that you refer to the manufacturer’s website, as they typically offer online technical support pages where software drivers, updates, and other related information can be obtained. You need to contact the OEM of your equipment directly as we are unable to support our chips once the manufacture has modified them for their particular use.
