If you dont have an external 32Khz crystal for the nRF52832, besides the higher power consumption, are there any other issues ? e.g. CPU starvation affecting my app during recalibration, how does recalibration affect longer running operations like DFU or data uploads, are connections more stable with an external crystal, etc.
There was a post about the power savings for the nRF51 but I have not seen any info about the nRF52. It seems as if the temp is stable enough then the power savings is not too much. Could the CPU temp change more and kick off calibrations when the CPU is busy computing a lot ? (say 10ms every 80ms) ?
Thanks Shannon
