Hello,
We are evaluating a new design using the nRF52382 (currently on a Rigado BMD-350 module) and we will have to use the GPIO near the radio due to the number of GPIOs we will need.
We have a some flexibility of what to use, and I would like to know which one would be the one that would affect less and be less affected by the radio comunication.
Analog measurement. Would radio communication would cause a lot of noise on the analog measurement?
Low frequency input with low current. We have a few signas that are very rarely toggled as one that will inform that the battery is charged, another that will inform that an external power was connected. Would any of these have high impact on the radio communication?
Low frequency output with low current. We also have some signals that are toggled with very low frequency, as a signal that is toggled every minute to enable the battey measurement (connected to a mosfet gate). The other one is toggled randomly but with low frequency, (no more than 10Hz) to enable an IC.
Any suggestions regarding these signals and their impact on the radio?
Finally, down to what frequency would be safe to no impact on the radio (considering just low current signals)?
Regards,
