Question regarding crystal

[Rajneesh]

Hello Nordic Team

I am working on Raytac MDBT42V – 512K module. In this module doesn't have external crystal. So according to Raytac spec, it recommend to use internal 32MHz crystal.

When I am downloading any nRF52 application it doesn't broadcast. So, which configuration do we need to change regarding crystal to make it work.

Here is the like for Raytac "MDBT42V – 512K" module spec: https://www.raytac.com/upload/download_files/03056be9fb6b807f9344a27b3bbc0e02.pdf

Any help will be appreciated.

Thanks

Hi,

 

Any application requiring the radio to be used must use a 32 MHz crystal. This should be present on the module so you do not have to add one externally to the crystal.

 

To verify if the radio is running or not you should try to set up a TX carrier, e.g. by using the attached hex file. You do not need a spectrum analyzer, just measure the current.
