I scan and I can find dfutarge , Master Control could not conncect automatically. I must connect it by myself. So how can i solve it?

Hi WYL,

Could you describe the issue more clear ? Prefer by step by step with description.

Are you testing with buttonless DFU ?

Have you also tried with nRFToolbox instead of Master Control Panel ?
