Can you please explain Bluetooth qualification process when using BLE chip?

Are there any shortcuts? The questions reach me by email.  Your selected IC  is a fully qualified Bluetooth v4.0 low energy design and combines the Radio, Link Layer, and Host into a single EPL (End Product Listing) enabling designers to easily create new Bluetooth end products without additional listing fees. Nevertheless for your radio device […]

How to connect your embedded antenna with your wireless module? EA#

Transmission line: The PCB track between GSM module and embedded antenna PCB trace impedance / transmission line calculators If there is no coaxial cable between your antenna and the GSM module then there is often a PCB track. A coaxial cable has an inner conductor, an isolator and a shielding. GSM modules or other wireless […]
