PREREQ: The Bot Phone must have 1.175+ to do the following steps
Via the Bot Phone, download the .pnf firmware at https://marksetbot.azurewebsites.net/d
There are two main branches of ProNav firmware: FW 1.x and FW 2.x.
There are also two generations of ProNav hardware available: HW0 and HW2.
As a general rule of thumb, any hardware made before 1/1/2020 is HW0 and anything after that is HW2.
The same updater is used for both but the steps vary.
If you are running FW 1.x, you should upgrade to FW 2.x. FW 2.x has many improvements but most notably improves GPS and compass code for long term anchoring stability.
You can tell what generation you are running based on the name that shows up when the updater does a device search.
If you are running HW0, you will see something like "PRONAV00646" where 00646 is the serial number.
If you are running HW2, you will see "ProNav MSB" or "ProNav Central"
MAKE SURE TO KILL THE BOT PHONE APP BEFORE DOING THESE STEPS
For HW 2 showing "ProNav MSB" or "ProNav Central"
NOTE: If you have trouble in the updater with Bluetooth discovery happening, go to Settings > Security & Location > Location and enable location services (this is done automatically in Bot Phone 1.262+)
For HW 0 showing "PRONAVxxxxx":
