Thanks! i found the reason for failure,beacause code is too big.But now,i face a new problem:when i update firmware,it workwell with new firmware.then,after power restart,my device was advertising as "DfuTarg" again not running my new firmware.
Thanks, Aryan! i resolved this problem with my friend's help.My button conflicted with my bootloader.But now,i face a new problem again:i update nodirc sample successful with dfu,but can't update my firmware successful.The DFU APP log as follow: [DFU]connection failed(0x81):GATT INTERNAL ERROR
