FOTA smp_svr example sdk 1.6.1 problem

[Fb62]

Hello,

I tried the smp_svr example with the nRF52-DK of sdk 1.6.1., i compile the solution whit segger v5.50c

I connect with the NRFConnect Device Manager app,

I try the echo test,

the connection status changes from disconnected to initialization,

but I don't receive the echo  and after some time I get GATT TIMEOUT ERROR.

Could you tell me how to solve this problem.

Thanks in advance.

Hello,

I resolved adding in prj.conf, these three line:

#CONFIG_MCUMGR_SMP_BT_AUTHEN=n
#CONFIG_BT_BUF_ACL_RX_SIZE=252
#CONFIG_BT_L2CAP_TX_MTU=252

best regards
