gettng NRF_ERROR_NO_MEM when initiating a bond in Peer Manager

[Jim Dattolo]

I'm starting to get things moved over to Peer Manager in SDK11 and when I call pm_conn_secure I get NRF_ERROR_NO_MEM. When reading the manual it states that this error means:

"NRF_ERROR_NO_MEM If there is no more space in flash."

flash? Doesn't the bond information go into the fsd file system on fstorage? Is there some config that needs to happen to make things fit?

I have 11 custom UUIDs discovered from the custom service on my peripheral role radio code when I make the call. Is there some limit on the amount of data that can be cached? Im running on a NRF511422XXAC device.

The bonds is stored in flash. Fstorage is short for Flash Storage. FDS uses uses Fstorage. The default amount of flash used by FDS of nRF51 is 3072 bytes. Check out fds_config.h. Are you sure you only have one bond stored? Does this happen also happen after an erase all?

[Jim Dattolo]

it doesn't ever work even after erasing the bonds. I don't have things in place to allow for a user erase so I just put in an erase on every boot and nothing chnaged. Is there something I need to do to locate the FDS in the linker file? I can start looking to see what my flash size is at. Things were really empty before moving over to SDK11 and peer manager. It might have filled up.

You don't have to do anything special. This tutorial should include what you have to do to get the Peer Manager to work.

I did all of that and the peripheral role code is up and running. Did it to my central role code and it fails on the no mem error. How does the peer manager use flash if there isn't any linkage? If we are running out of flash memory then it should never have linked. It sounds like peer manager and fstorage is assuming something and hard coding flash sectors. I'm going to keep looking at the map files, however if there is some area I need to stay out of I need to know that.

[Petter Myhre]

Yes. They are assuming something. And they are hard coding flash sectors. The default amount of flash reserved by FDS on the nRF51 is 3072 bytes, as I mentioned above. Would it be possible for you to share your project files so I can test here? You can do it privately through your MyPage at nordicsemi.com if you want.
