Hi

Could you please check out this current consumption guide, as it describes very detailed most ways to reduce the current consumption. Especially connection parameters and advertising intervals might be interesting.

If the high consumption persists, could you test your application on a Development Kit as well, to confirm whether this is a software or hardware problem?

Best regards,

Simon
