Hello,

Does anybody knows how to free memory that is created/occupied by calling

ble_gattc_read()

?

Function

Code: Select all

ble_gattc_read()

, calls

Code: Select all

ble_gattc_proc_alloc()

, and inside that function it is called

Code: Select all

memset()

.

How do I free that allocated memory? I get error with error code 6, which is

Operation failed due to resource exhaustion

.

Thanks for any help.

I found solution with help from this example https://github.com/espressif/esp-idf/bl ... ain.c#L375.

Problem is in that when to call multiple times to read. Not to call all in

Code: Select all

OnDicComplete()

function, but to called it after the read is over. You have to make a chain, when one read is over.

Also, i made a mistake in a previous post. Memory is not allocated in

Code: Select all

memset()

, it is allocated in function called before, it is in

Code: Select all

os_memblock_get()

.
