Setting command block with preset commands in Minecraft PE? [duplicate]

I have seen posts of people that are trying to put command blocks in their world with preset commands in the blocks, and they claim to have them work, but I am having trouble doing the same thing in the Pocket Edition of Minecraft. Usually it says that the “{“ character is unknown, creating a syntax error.


PE has no NBT, that's why this doesn't work. The command in the command block is an NBT tag, which you can't set in PE.
