Advertising doesn't change name after code update

Question

Greetings, 
 
 I've been developing a DFU firmware that should update the device through Android. The thing is, the device works, but I changed the advertising name, and it still shows the old name when I try to update the device. I use the following function to update the name: static void make_dev_name(void)
{
 ble_gap_addr_t device_address;
 uint8_t companyName[] = {"M"};
 uint8_t modelName[] = {"1"};
 uint8_t *macAddressName;
 uint8_t macTmp[12];

 sd_ble_gap_addr_get(&device_address);
 macAddressName = Convert_Hex_To_Ascii(&device_address.addr[0], 4);
 memcpy(&DEVICE_NAME[0], companyName, 1);
 memcpy(&DEVICE_NAME[1], modelName, 1);
 memcpy(&DEVICE_NAME[2], macAddressName, 12);

} 
 
 Any idea why this issue occurs? 
 
 I used reference from here; https://novelbits.io/ota-device-firmware-update-part-3/

Ok, so I finally found the culprit behind this. It's actually the UART. Because the UART needs to communicate with another controller, I assume it compares the advertising value from the flash on the other chip with the one from Nordic and overwrites it. When I disabled the UART init, the code works as it is intended.
