Dear Andreas,

Thank you for your answer. It comfort my first idea.

The second point is about a problem between the shared variables into my different libraries. But I have bypassed the problem by another implementation.

Sincerely,
Sylvain.

Hi Sylvain.

The API function sd_ble_gatts_value_get() is used to get the value of a given attribute from the server, ref: infocenter.

It is used locally, so you don't get data from the server to the client.

If you want to read/write from a client to a server you have to use sd_ble_gattc_read() or sd_ble_gattc_write().

[quote user=""]The strange problem is that when I read the value in debug from the main I got the right value, but when I look the value from the library it's always 0. I really don't understand since this is the same variable.[/quote]

I'm a bit unsure what you mean, could you explain more?

Best regards.

Andreas
