MCUMgr failed to connect to peer after 10 sec

[Markus Arnoldsson]

Hello!

I am trying out the SMP Server sample. I have it all built and flashed on my nRF52DK and have tried the echo command using the nRF Device Manager on iOS which worked.

I now want to try it on MACos running the following command:

sudo ./mcumgr --conntype ble --connstring peer_name='Zephyr' echo hello

Upon running this, I get the error: 

Error: Failed to connect to peer after 10s

How can I solve this?

I don't have a Mac to test on, but I just tested this on Linux Ubuntu an was able to get it to work, I did the following:

• Built and programmed the smp_svr (NCS v1.9.0) onto the nRF52840 DK using the command under SMP SVR --> Building the sample:
  • west build -b nrf52840dk_nrf52840 -d build_ble_52840 -- -DOVERLAY_CONFIG=overlay-bt.conf
  • cd build_ble_52840 && west flash
• Tested the echo command using the command under SMP SVR --> Sample image: hello world!
  • sudo /home/simon/go/bin/mcumgr --conntype ble --connstring ctlr_name=hci0,peer_name='Zephyr' echo hello
    • Got the response "hello" back

Not sure why it doesn't work for you. Could try to add --loglevel debug to the mcumgr command? Could you also try to debug the nRF52 DK and enable logs, to see what's happening on that side.

Best regards,

Simon

I decided to try Linux ubuntu instead. This worked, so something wrong on the Mac, will not delve further into it tho.
