Device status vector

The current flags status is represented on one byte and it is returned on config:

bit_sensor  = 0;    // sensor fail/ok
bit_paired  = 1;    // bluetooth paired
bit_wan     = 2;    // internet access
bit_cloud   = 3;    // publish cloud
bit_code0   = 4;    // code bit 0
bit_code1   = 5;    // code bit 1
bit_code2   = 6;    // code bit 2
bit_code3   = 7;    // code bit 3

The error codes are represented on up four bits. Error code table:

ecode_sensor_ok          =   0;
ecode_sensor_read_fail   =   1;
ecode_sensor_timeout     =   2;
ecode_wifi_fail          =   3;
ecode_ifdb_write_fail    =   4;
ecode_ifdb_dns_fail      =   5;
ecode_json_parser_error  =   6;
ecode_invalid_config     =   7;
ecode_api_write_fail     =   8;

sample:

    00000011 -> sensor ok, device paired
    00001101 -> sensor ok, wan ok, ifxdb cloud ok
    01000101 -> sensor ok, wan ok, ifxdb write fail
