nrf5340 - running the complete BLE advertising and handling the read / write gatt client processing running in network core and doing rpc to application core

Create a sample application for BLE advertising running the BLE gatt client on network core and just debug print on application core

Issue is the ble advertising is not getting discovered when running on the network core

here is the code attached for network core example

trynetcore.zip

Here is code attached for cpuapp core example

trycpucore.zip

we want to utilise the netcore cpu&ram and do the ble processing on nrf5340's network core since we are running out of RAM after adding WiFi functionality in nrf5340's app core. Please help, I am unable to debug this issue, same netcore sample if changed board to cpuapp it works correctly!

Hello,

Can you confirm that using the example as-is works?
https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/samples/bluetooth/rpc_host/README.html#ble-rpc-host 

Are you running on an nRF5340-DK or your own hardware? If you are using your own hardware, do you have external 32kHz or not, do you have DCDC circuitry or not?

Hi Kenneth, I am running on eval board ( nrf5340-dk ) and using sdk 2.7.0

I tried 2.9 that is working, but since my wifi is using 2.7 sdk it is big change to move from 2.7 to 2.9 sdk.

Is there any issues in using 2.7 sdk bluetooth on network core?

I know the remote procedure call libraries have gone through some updates, so it may be that some issues have been fixed in the process, you may try v2.8 also.
