@Hung Bui what do you mean by The DFU master won't base on the name of the advertising name to find the bootloader !!! I put the peripheral on Dfu mode by writing on the Bootloader service (second charact), then disconnect then the peripheral advertise DfuTarg, then I connect to it and upload the new app. if the advertising name is different from DfuTarg it wont connect (I connect only to DfuTarg)

Hi @Hung_Bui . It seems that the nrf toolbox app's dfu doesn't work on ios but it does on android, could you confirm ?

Hi Mango922, Yes, you can use the scan response packet for the device name (or the 128bit service UUID), make sure you don't also use it in the advertising packet.

I don't use iOS much and don't know what Swift is but I heard that switching off and then back on Bluetooth on iOS helps with cache. If you paired device you need to "forget" it.

Oh, you pointed my problem correctly.

I defined the device name 9 digits. I totally forgot to calculate the length.

Then if I still want to use this 9 digit name,

adding ble_advdata_t scanrsp may do the trick, does it?

Didn't know that. Thanks for telling me.

Have you tried Swift? I'm curious whether a method to clear cache in iOS exists or not?

Do you know methods that will do things like this?

Android Toolbox clears cache if you close and open it again.

Hi Mango,

The DFU master won't base on the name of the advertising name to find the bootloader but on the Address and the 128 bit service UUID in the advertising packet.

So it shouldn't be a problem to change the name of the bootloader.

However, since the 128 bit service UUID is included in the advertising packet, the length of the bootloader should be short. It should not be more than 8 digit otherwise you will have an error when start advertising.
