Hi,
We are currently using the NRF52832 in one of our products. Due to software requirements we need more RAM. Therefore the product is going to be redesigned for the NRF52840. In order to put our updated product on the market we are doing a risk analysis to see if we need to repeat any EMC / RED testing on our product. Based on the available Nordic documentation there does not seem to be a difference in the radio implementation. In that case we can suffice by making a risk evaluation.
Can you confirm that both products (NRF52832 and NRF52840) use the same Radio frontend / implementation?
Please let me know if I need to supply more information.
