How to add custom hci_rpmsg message ?

[jchan12345]

Is there any example of adding custom hci_rpmsg message ?  I want to send three numbers(x, y, z) coordinate from NetCore to AppCore using hci_rpmsg through shared memeory. Thanks

Hi,

Are you looking to alter the existing hci_rpmsg sample to add this functionality, or are you looking to write a net-core application which uses the rpmsg service to send data to the app-core application?

For the second situation there is a sample at zephyr/samples/subsys/ipc/rpmsg_service which should cover that.

I got the RPMsg Service [master] started,  but where is the sample code for the remote ??

Starting application thread!

RPMsg Service [master] demo started

-------------------------------------------------------------------------------------------------------------------------------------------------

According to document https://docs.zephyrproject.org/2.7.0/samples/subsys/ipc/rpmsg_service/README.html

There should be another demo running in the remote (NetCore ?), but I could not find the source code having

printk("\r\nRPMsg Service [remote] started\r\n");

in any main.c

Need to write my own code or there is a sample code somewhere in Nordic website.  Any suggestion ??  Thanks.

Never mind.  I found the code.  It is in the remote folder

Having both     CONFIG_BT=y    and  CONFIG_RPMSG_SERVICE=y  in prj.conf  will cause IRQ conflict in building sw

gen_isr_tables.py: error: multiple registrations at table_index 42 for irq 42 (0x2a)
Existing handler 0xa087, new handler 0xa087
Has IRQ_CONNECT or IRQ_DIRECT_CONNECT accidentally been invoked on the same irq multiple times?

I need BT because the bluetooth radio is attached to the NetCore of nrf5340.  The blue tooth sw stack  may be using RPMSG and I need RPMSG_SERVICE to send my own data from peripheral attached to NetCore too.

You may close this ticket.   I am able to add another endpoint for my app in addition to the original endpoint for BT The hci_rpmsg is working fine for my app communicating between AppCore and NetCore. of the nRF 5340
