David,

The module that you are using is certified as a mobile device.  This means that the radiating element of the radio has to be 20 mm from the body.  The power output from this radio and a Bluetooth radio together will require SAR testing to show compliance with the RF exposure requirements.  I can get a quote for this testing, but it will take a day or two.

The module will require what they call a class 2 permissive change.  Only the Grantee can apply for a permissive change.  Of you are working with them they might help you out with that.

It is more common for the manufacturer to allow a “change of ID” which would allow you to have your own grant for the module, then you could apply for the permissive change to certify what you want to certify.

I can be available to discuss this with you if you have any questions.

Let me know how you would like to proceed.
