Hello,
The question might be a little vague at the moment but I would like your guidance if possible.
I already asked other questions related to this topic but I will once again leave you with some contextualization:
At my company we developed a product that is based on your NRF52832 microcontroller. We are currently entering the certification phase under the RED directive and are in extensive talks with the Laboratory that is guiding us through the process.
In one of the last conversations that we had with them they told us that we had to ensure 3 modes of operation for the BLE chipset:
- Continuous Transmission
- Continuous Reception
- Real Communication
*Changing from one mode to the other could be done by reflashing the DUT.
At the moment we are enviosioning a setup where we would have two of our products communicating with each other.
Operating modes:
-
DUT constantly transmitting data and a companion device somehow signaling the proper reception of that data
-
Companion device constantly sending data and the DUT will somehow signal that it is properly receiving that data
-
DUT and companion device will exchange messages alternately, with both signaling the reception of valid data.
- Do you see anything wrong with these test scennarios?
- Do you think that we are going towards what is intended by the test Lab, or from your experience with these matters do you think that they are expecting something entirely different?
Given that there isn't much information directly correlated to our situation I would really like your comments on this topic. In fact, when searching for information about this topic all that can be found is related to the new RF Receiver Blocking test, and nothing that resembles the modes that I listed above. Apparently, given all the information that we have already provided the certification entity, we won't have to do the RF Receiver Blocking test. However, in the possibility that we do have to do it, I would also like to have your opinion regarding this test's setup.
- We don't have access to the UART pins on the chipset as they are already allocated to a different peripheral. From what I understood, the DTM example you provide requires access to a UART interface. With that being impossible to do, how can we go through the RF Receiver Blocking test?
Please give some feedback regarding the topics listed above and then if you wouldn't mind I would go into some more details regarding implementation.
Thanks in advance for your time and the help that you have already given us. Please keep up the awesome work that you do here in the forum.
Best regards,
Simão Pinheiro
