The tribute took place before rapper Abra Cadabra’s set on the Pepsi Max Arena stage at the festival in Finsbury Park over the weekend.
He tweeted: ‘I’m going to be dedicating a minute of silence for all the victims of the Grenfell tower and Bradley Lowery at @WirelessFest today.’
Six-year-old Lowery died from neuroblastoma, a rare form of cancer, on Friday.
His mother Gemma Lowery wrote on Facebook: ‘My brave boy has went with the angels today 07/07/17 at 13:35, in mammy and daddies arms surrounded by his family.
‘He was our little superhero and put the biggest fight up but he was needed elsewhere. There are no words to describe how heartbroken we are.’
At least 80 people have died and over 70 were injured in the Grenfell Tower blaze last month.
The fire at the 24-storey building in north Kensington, London, was one of the worst disasters in modern British history.
Singer Lily Allen previously claimed the number of victims from the blaze was being ‘downplayed’ and that the real death toll is closer to ‘150 people’.
