Protocol used by GPS tracking devices manufactured by Skypatrol headquartered in the USA.
flespi parses the Skypatrol protocol messages into a JSON object with the
fields listed below in the Parameters tab.
To connect your tracker using the Skypatrol protocol, you need to have a skypatrol channel created first.
Point your tracker to the channel's domain name:port via SMS or configuration tool provided by the vendor.
Then create a device instance for your tracker and use a 15-character IMEI (usually specified on the tracker casing) in the ident field.
Use the Toolbox tab on the device screen to check if the messages are coming.
There are two separate variations of the protocol and one should be correctly selected in the channel configuration under 'Protocol version' setting:
- '5-byte header' — for Skypatrol TT8750+ devices and analogs (more modern version, try it first)
- '4-byte header' — for Skypatrol TT8750 devices and analogs (older version, enfora types of devices)
For Skypatrol devices to work correctly via skypatrol channel, they should be configured as follows:
'5-byte header' devices:
Keep-alive message mask must be = 7:
- bits enabled:
- bit0 — binary format
- bit1 — add param1 to keep-alive message
- bit2 — add device ID to the keep-alive message
- bits disabled:
- bit27 — do not add a mask to keep-alive message
- bit28 — do not add sequence number to keep-alive message
Position message mask must have bit27 enabled — add report mask to position messages.
'4-byte header' devices Output Event 52 Parm2 bit field:
- bits enabled:
- bit1 — Parm1
- bit2 — modem ID
- bit3 — IO data
- bit7 — event category
- bit12 — GPS data
- bit20 — odometer
- bits disabled:
- bit0 — ASCII format
