Do you have two files with those definitions?

Code: Select all

const uint8_t REMOTE_SERVICE_UUID[] = {0x00, 0x03, 0x5b, 0x03, 0x58, 0xe6, 0x07, 0xdd, 0x02, 0x1a, 0x08, 0x12, 0x3a, 0x00, 0x03, 0x00};
const uint8_t REMOTE_NOTIFY_CHAR_UUID[] = {0x00, 0x00, 0x29, 0x02, 0x00, 0x00, 0x10, 0x00, 0x80, 0x00, 0x00, 0x80, 0x5f, 0x9b, 0x34, 0xfb};

Try to remove const word.
