we at PHYSEC have purchased two Nano BLE 33 Sense boards as part of a research project. We would like to use the board for wireless sensing. Unfortunately, the RSSI values that can be read out with a Bluetooth connection are not sufficient for this. Therefore, we would like to know if it is possible to get channel state information from the device that are measured during a Bluetooth LE connection. We have not found anything about this in any documentation and therefore wanted to contact you directly.
What kind of information are you looking for? From an application point of view RSSI is the only information useful for end users that can be informed that the connection maybe lost if they move their devices e.g. mobile phone.
You are not really contacting anyone directly here. Most of us are just Arduino users helping each other.
If you want to work with the radio directly you could ask the Nordic guys who build the nRF52840 chip. I would recommend to study their documentation first to show you have done your homework.
Thanks for your Answer. I've worked with the nRF52833 Chip before and it provides an option to sample IQ-Data. This is done by sending a packet with a continuous tone extension. I'm searching for an equivalent function on this Board , since it is based on the nRF52840 from the same family, but i have found none.
