RE: MCUMgr failed to connect to peer after 10 sec

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

Hey! I tried using --loglevel debug quickly. Maybe you can find something useful here?

I am going to try reinstalling the SMP server and doing exactly as you did

markusarnoldsson@Markuss-MacBook-Air ~ % sudo go/bin/mcumgr --loglevel debug --conntype ble --connstring ctlr_name=hci0,peer_name='Zephyr' echo hello

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
