how to send a notification enabled response, or service initialized indication for the BLE SMP service

[ziv123]

hello Nordic

i am working with nrf52840 running ncs v2.8.0 

this device connects with a central, via BLE, the central running on linux.

i am working with smp (simple management protocol) with some user group id and also some build in groups. 

the problem i have is that when the 2 device establishes a connection then the linux side is ready faster then the nrf and if i send a message then it is not received in the nrf device which is nor ready yet for receiving (if i put a hold on the send for 2 seconds then all is fine).

i want the nrf device to send some "is ready" message indication to the central (by it self, not as a replay to a command sent from central) once the SMP service is initialize, or notifications on it are enabled. since the SMP service is initialized and built with in the ncs (which i don't want to change internally) i wonder how this can be done, i think there are some api in more advanced ncs versions but for now we are working with ncs2.8.0

hope you can help 

best regards

Ziv

Hi,

I am not sure what this not ready state could be. Configuration of services happens before the device starts advertising, so that should be OK. I sthe problem that some procedures has not completed, or something else? Can you share a sniffer trace and log from the problematic case so that we can understand more about what the root cause here is?
