ERROR 4 [NRF_ERROR_NO_MEM] when connecting to nRF connect mobile application

[Msk]

I'm trying to merge the ble_Central example project with ble_app_template project. I've added 3 Custom services in the ble_app_template project by setting UUIDs and trying to send and receive data using nRF connect Mobile application. Everything works fine in with ble_app_template project alone.

When I merged it with ble central scanner project.it starts advertising and I am able to see the nRF device advertising in the nRF Connect app , however, whenever I try to establish connection with the device, it crashes and gives me ERROR 4 [NRF_ERROR_NO_MEM]. I'm using nRF52480 with SDK17.0.0. Can any one help me what causes this error.

Thanks in advance.

Hi

Please note that if you're using SDK v17.0.0 it is strongly recommended to switch to v17.0.2, as it is a bug fix release replacing v17.0.0. 

This error seems to be due to the SoftDevice not having enough memory, so I would suggest increasing it further to make some room. If that doesn't help either I would try debugging step by step to see where exactly this goes wrong, but I'm guessing it doesn't have room to store the connection information.

Best regards,

Simon

Hi

I changed the SDK to v17.0.2. Didn't make any difference though. Also how and where do I increase the softdevice memory? And what value of memory I should allocate, as I don't get any specific memory suggestion in the LOG rather than ERROR 4.

Thanks.
