Hi to everyone,
I'm reading UM-B-006 for implementing sleeping funcionality on my project.
I want that application modify dinamically sleep modality, so in according with doc, da1458_config.h is:

/*Sleep modes*/
#undef CFG_EXT_SLEEP
#define CFG_DEEP_SLEEP

when the application start for the first time, sleep mode must be set to extended, so in app_set_dev_config_complete_func I put this:
app_set_extended_sleep();

Hi Dialog.
To differnt SDK5.x and SDK3.x, I found "APP_PARAM_UPDATE_REQUEST_TO"
I think this value is timer for connection parameter update request.
My question is why this value is 10sec? It so to late..
Is this minimum value?
In my case, I use SDK3.0.10.x and I was maked same timer for connection parameter update request.
and vlaue is about 200ms

Which value is correct?

Thanks

How many adv packets can DA14580 receive in each scan window?

Dear Sirs,

Assuming that there are many peripherals in the area,

Q1: how many adv packets can central device receive in each scan window? I mean if scan window is long ebough, central device
can get many adv packets from different perhipherals or each one scan window can receive only one peripherals's adv pacjket?

Q2: How long is the kernel overhead to retrieve adv packet?

Best Regards,

Is there anyone who have succeeded to get the SERVICE_CHANGED indication in GATT?

Hi, all.

I am trying to get the indication of SERVICE_CHANGED characteristic in GATT.
But I have not succeeded yet.

As described in RW-BLE-GATT-IS.pdf, I have tried to send GATTC_SVC_CHANGED_IND_CMD message to TASK_GATTC from TASK_APP with parameters below.

req_type -> GATTC_SVC_CHANGED or GATTC_INDICATE.
svc_shdl and svc_ehdl -> The range of all characteristic handles I use.

Of course, I enabled CCC descriptor of SERVICE_CHANGED characteristic from client Android application.
