CC2640R2F: SC_EVT_SCAN_DISABLED is not getting called

San Joy

Part Number: CC2640R2F

Hey there,

I am using CC2640R2F, SDK:2.40.00.32

I have made DEFAULT_DEV_DISC_BY_SVC_UUID as FALSE to scan the peripheral devices.

I am enabling SimpleCentral_doDiscoverDevices(0); in GAP_DEVICE_INIT_DONE_EVENT and I can able to discovere the devices and can see their mac ids in SC_EVT_ADV_REPORT.

My doubt is after discovery SC_EVT_SCAN_DISABLED should get called.

In some of discovery cases it is getting called and some of the cases it wont get called.What would be the reason for not getting called?

Thanks ya.

Hi San,
That is a good question, which I do not have an answer for yet. Have you tried with a later SDK? How easy is this to reproduce?

-I didn't try with later SDK
-Just enable the scan (frequency which I observed is :4 times out of 10)

Also I want to share

I am copying data from the discovered devices in a function which is called in GAP_DEVICE_INIT_DONE_EVENT.

does this is responsible for the issue caused ? We can not perform any operations while discovery ?

Hi I am still waiting.
Have you come across any solution ?

Hello San,
I am looking in to it.
What do you mean by copying devices from function called in GAP_DEVICE_INIT_DONE_EVENT?

How can it be reproduced on simple_central?
It can happen if you run out of heap, then you might receive a GAP_EVT_INSUFFICIENT_MEMORY (SC_EVT_INSUFFICIENT_MEM).

I am copying pMsg->pData for discovered devices in an array.

Thats what I am doing in SC_EVT_ADV_REPORT.

Hi Erik,

How can it be reproduced on simple_central? --------Do some action in SC_EVT_ADV_REPORT when device is getting discovered.Lets say copy the pMsg->pData into array OR print the pMsg->pData for the devices

It can happen if you run out of heap, then you might receive a GAP_EVT_INSUFFICIENT_MEMORY (SC_EVT_INSUFFICIENT_MEM)-------No I am not receiving this event

As I told above 4 out of 10 cases this is happening.Other cases I am getting SC_EVT_SCAN_DISABLED event.

Hello San,
I am not able to reproduce this in simplelink_cc2640r2_sdk_3_10_00_15. Can you try to reproduce this in sdk 3.10 and then upload the modified simple_central.c file you use to trigger the issue so that I can test?

Also how many devices do you discover when the issue occurs?
