Live configuration of the nRF52832 Soc. using Bluetooth protocol and on & off modes

[Masoumeh]

Hi.

Hope you are well. 

I intend to use the nRF52832 for a wireless neural recording system and I need the nrf to do some works for me, such as:

1. putting the system in on and off mode through wireless connection, i mean i want to send the command by Radio transceiver to nRF52832. 

2. changing the configuration of the nRF52832 by its radio transceiver.

the main question is that does the transceiver of the nRF52832 works in system on sleep mode? or does it have such mode like it? 

Also I have another question. since the size of the final system and the placements of the components are very important to me, I am going to design a PCB that includes both my front-end part and the BLE set up. so I am not using the DK provided by different companies. how can I config the nRF52832? my decision was to use Keil, but I don't know how to start, because most of he example codes are for development kits. 

respectfully

I strongly recommend using a DK to build the labratory prototype / test model with the development board from the analog frontend (will be a "mess of wires" prototype). This allows you to build upon existing examples and get to know how "stuff works" by looking at the code and how it performs in the real world. Otherwise the nRF SDK can be a bit overwhelming.

Using softdevice and bluetooth allows low-power wireless connections - while the radio cannot work in sleep modes, it can be turned on and off very quickly. Low bandwith applications thus use the radio only for a very minor fraction of time.

Transmitting EEG signals over bluetooth will exaust the available bandwith rather quickly. A few data channels might be possible, but will use significant bandwith (and energy).
