thingy52 dfu

Question

Hi ! 
 Regarding the dfu upgrade service of thingy52, I would like to ask if it is possible to use some Bluetooth devices (such as laird's bl654) to make thingy52 enter dfu mode by writing gattc commands. I have seen the code of thingy_sdk_v2.1.0, know the operation code sent by the official app(android nRF Connect),i tried to use the gattc write command to write the operation code to the characteristic, but did not enter the dfu mode, Does anyone know why?

i got the problem work out already today！ My guess is correct，you can write opcode to the characteristic by gattc write commands ,but you must ensure the opcode is correct and the characteristic you write is correct
