MACos - Echo hello returns error: Failed to connect to peer after 10sec

[markusarnoldsson]

Hello!

I am using the SMP Server sample from Zephyr on a nRF52DK. I can send echo command through nRF Device Manager successfully.

However, doing it on MAC returns: Failed to connect to peer after 10sec.

I am using this command:
sudo ./mcumgr --conntype ble --connstring peer_name='Zephyr' echo hello

I am using Go version 17 and installed mcumgr by writing:
go get github.com/apache/mynewt-mcumgr-cli/mcumgr

Any idea what the reason could be?

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

Error: Failed to connect to peer after 10s`

[rjain0000]

I am facing the same issue.

• at first, mcumgr just killed with -9. Then I found permission issue for BT.
• after this I get the same error.

Anyluck ?

Hello!

Sorry no luck. Since I had some time constraints I ended up using a Linux computer instead where it worked as expected.
