need exact example to follow for our development need

[JIVAN]

From you last reply to earlier ticket now i am able to follow and reading your programs
understood quite some part of the flow. Still its not very straight forward

I checked few examples under peripherals. I will explain my scenario
please suggest appropriate exampel to use as base code

Also want to study about SoftDevices and various versions
Please give a link to document about it
Also want to know about the directory structure.
Under any examples there are various folders
pca10040
pca10040e.. etc
Please let me knwo about the significance of the same

Any document you have as what is the highlight of the
various examples

Finaly our requirement is

1. Read analog input from the temperature sensor
2. Keep the counter of minutes running always
it should count minutes even in sleep mode
so please suggest the proper sleep mode. It can
wake up every 5 minutes. If temp is normal then sleep again
3. For each rise in temperature we store the minutes count
as time stamp, as we not using external RTC. So use
RTc (which is a counter in 52810 case )
4. Again sleep after recording the event mark as start
detected.
5. For further wakeup we check if the temp is gone below
a set point so we mark it as off and store this
information with RTC count
6. This will keep happenng all time

This was the processing part now the BLE part

We have to wait for the connection to the central. The
central will not be available always. So we need a method to know
if the central is now available

(i am not sure how the communication will work )
Ideally i want the peripheral to wake up when it detects
the central in vicinity. Is this possible?

If yes tell me proper example for the same.
If not then one way i feel is we start the advertising
and wait for the central to connect If no connection
or no command from central then sleep again and wake up
and try again.

For the above working please suggest the appropriate example
or examples to follow.

Hi,

The pca10040 is the same as the nRF52832-DK. You can find the PCA number printed on the white sticker on the DK.

We don't have any examples that does exactly what you want.

You can find our BLE examples here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/examples_ble_peripheral.html

The ble_app_uart example is often a good starting point. I recommend that you test and study that example.

Problem is under peripheral there are so many examples and not easy to understand what each one does. If you have a summary of each example so we know what all features or flow of the example is and choose accordingly. Or referening to our main line of problem of connecting to central when its available please suggest  application/s 

And please suggest and example for FDS

Hi,

You can find the documentation for each example on infocenter.

You as a Bluetooth peripheral does connectable advertising if you want a central to be able to connect to you. You just advertise until the central connects. You will get a connected event when the central connects.
