ProTool from Bimmergeeks.net sure looks promising. If I wasn't already immersed in the ISTA/NCS software, I'd take a hard look at ProTool.

Pfffft ProTool is bullshit

from their website...

Coding Support
Most Bmw, Mini or Rolls Royce Models EXCEPT older chassis such as E46, E39, E38, E53, E85 and anything older.

It's useless to "us"

monitoring my E53 model is limited by a lack of capable apps
 

A lot of easy-to-use Android apps (not sure of apps for I-phones) are available to read and clear codes, but very few can do more, for the E53. I've tried three so far, but BMW PID's are limited, so I've been stymied in my search for basic gauge substitutes https://xoutpost.com/bmw-sav-forums/...l?nojs=1#links. So far, my expenditures have been small, so no harm done.

• 1) BAXF obd2 dongle ($20, bought in 2013),
• 2) Torque Pro app ($5, also bought in 2013),
• 3) OBDLink LX dongle ($50 in 2014, now $60-70, bought in 2016) free app included,
• 4) "OHP INPA Cable FTDI FT232RL USB OBD2 for BMW Diagnostic Coding | K Line | Windows Only" ($32, Oct.2021),
• 5) OTG adapter, ($5, from 2017),
• 6) dedicated smartphone to the project, no SIM card, Samsung Sm-J327A (spare phone, bought in 2017 for $100)

Total expenditure so far is $212, but all can be moved to other vehicles, and/or used regularly in them.

I'm interested in the "Deep OBD" app I've seen on Google Play, but it looks to be over my head due to my lack of expertise in computer-ese (my last computer schooling was in Fortran & COBOL back in the early 70's, no training on modern computers...just picking it up a bit at a time). I don't want to buy another app to get limited or no coding access on my 2001, and so I'm done trying new Android OBD apps.

Currently I'm busy (slowly, repetitively) repairing the brakes/MC/ABS on my wife's Cobalt, to be followed by fixing vacuum leaks/DISA on my X5, so my quest for onboard data displays is at a halt. Coolant and Oil temps are all I've got visible on the smartphone, via Torque Pro. I've not tried seeing if the NT510E display will be visible to me while driving (not sure yet what data it will display, or if it should be running while driving...possible data interference).

My other plans include

• 1) using the Ibus (K-line ?) behind the radio and a Resler to display data on my Android devices,
• 2) buying my wife a new laptop so I can get her current laptop to use "ISTA,INPA, whatever" in-car, and
• 3) finally resorting to an Avin Avant Android head unit to get what I want to see (current radio is almost new, so it'd be a waste to chunk it out; if the PO returns the original radio, I'd like to re-install it, so the Android HU wouldn't be installed).

So, in the meantime, I'll have to settle for the Foxwell's slow but handy abilities as a handheld scan tool, and limited usage of my Android apps for (meager) data display, (some) live data while driving, and just wait 'til I make a step towards a more capable system.
