What Bluetooth SIG fees are required for a product that includes the Nordic nRF52840 chip? What about for a product that includes a 3rd-party Bluetooth module (that contains the nRF52840 chip)?NB: The product would only be for sale within Europe.I am concerned by the Bluetooth SIG "Qualification Testing" fees, which look prohibitively high, and could kill the project.Ref: https://www.bluetooth.com/develop-with-bluetooth/qualification-listing/qualification-listing-fees It isn't clear to me what &...

 Based on the Product Specification v1.0, the antenna load impedance should be 15Ω+j88Ω. I checked the antenna impedance based on Figure 32.  The simulation result is  For the differential impedance Zd, I used the following equation The simulated result is about 21Ω+j43Ω, far from 15Ω+j88Ω. Anyone can help to check this problem. I want to fine tune the external circuit based on the S11 of my own PCB antenna.  thanks in advance. -Tony...

From what I can tell, the SDK for Thread provided from Nordic uses a precompiled Openthread library that hardcodes the UART pin configuration. This means that users of this SDK must modify and recompile the library manually if they want to use the Thread SDK on their own boards with different pin configurations. The Openthread library is meant to compile as a platform independent binary, and the Nordic supplied SDK should include the specific lower layer code separately. This along with an application/boa...
