nrf52832 , switch central mode to peripheral mode

[guma]

Hi, 

I have to nrf52832 , s132 modules working as peripheral and central.

I would like to get an idea and input on how to change central mode to peripheral mode.

The purpose of my project is to fetch the advertising device RSSI (nrf52832- peripheral)and then forward(nrf52832 central mode to peripheral mode) the data to another BLE module and publish the data.

1) How to change the operating modes?

2} What are the settings that i should consider at the peripheral that is advertising?

3)How can i proceed ?

4) How can i send the RSSI values of the advertising packet, in the scan report of central after changing in the operating mode to peripheral to advertise that data?

Thanks,

Uma

Note that (some of) the SoftDevices support both Central & Peripheral at the same time - so no need to switch between the two roles 

Have you looked at the Relay example?

is there a way where i do not switch modes but send over the advertising device RSSI  in the scan report of central to other device?
How can do that.

As with any project, take it one step at a time:

1. Just Collect RSSI; store in an array (or whatever).
2. Just Transmit data - any data - from an array (or whatever).
3. Combine the two.

I am able to collect the RSSI values and transmit that data (the first half of the diagram on the left).

what i want to do now is i want hose obtained values to be sent over ble to another peripheral device.

To do this i need to establish connection right?

to get understand how i should proceed i tried to connect peripheral and central using gap connection , scan parametrs and i am able to connect obtain nrf success with sd_ble_gap_connect .

i am connecting based on peer address.

scan, get scan report, BLE_GAP_EVT_ADV_REPORT:, i called sd_ble_gap_connect and when success fetched rssi. The connected state BLE_GAP_EVT_CONNECTED, i don tget continuous.

So is this the correct way to connect?

how can i get continuously rssi values ?

Now I'm lost again!

In that diagram, everything within the red box is running on a single nRF device - isn't it?

If not, please provide a more complete diagram.

Like this?

I did go through relay example , let me know if i have understood it correctly.

The connection parameters, scan parameters , for central to scan a peripheral and connect.

The gap parameters and connection parameters are for peripheral to advertise and connect to central.

So combining the two together, and checking device state if central or peripheral and their respective events.

is what it refers to running both modes at the same time and there is no need to switch?
