Hello!
Some time ago, I bought Garmin Striker 4 (echosounder+GPS, no mapping).
Unfortunately, this device have no USB-ports and card slot and by this way the ability to upload tracks and way points to pc is absent. However, the device can share the data with the same Garmin Striker series or EchoMap echosounders through Garmin protocol (or Garmin to Garmin protocol?).

By this way, I guess, it is able to connect my Striker to PC through COM port using Garmin protocol. I’ve make hardware connection, but regular GPS programs can’t connect to it, possible because the connection protocol is some differ.
I’ve used COM port Toolkit to receive data from my striker. Then I turns on the Share Data option, it sends different 2 bytes messages every 10 s (in the end of this message).
I’ve sent HEX command (10 0A 02 0 00 ED 10 03) in order to download waypoints, but nothing changed. It looks like he need some initialization before accepting the commands.
I found the post on this forum, that looks like very promising and describe the behavior of the connection:

“The programming is trivial. You knock out the useless doubled 10s and
lower the count and you are on your way.
Be sure to ACK each packet for fastest throughput.
Source is available.
Mike”
However, there was no link on Source code or the direct solution of the problem.
I’ve read the Garmin interface protocol, but it’s hard to understand. In any case, it looks like Garmin to Garmin protocol is some differ.
Help me please with downloading waypoints and tracks from this device.
Signal output from Striker is given below.
With best regards,
Mikhail.
