SW-EN600-L controller with EP6 not working

[ole]

I have a bike with Shimano EP6 motor with a SC-5003 all-in-one display and a separate power button unit on the frame.
Tested a SW-EN600-L unit on my bike to be able to get bluetooth and use the E-Tube app, but I couldn't get it to work.

• SW-EN600-L won't turn on the bike with EP6
• Shimano lists SW-EN600-L as compatible with EP6 on their webpage
• My SW-EN600-L unit works fine on another bike (with EP801)
• If SW-EN600-L is plugged in while bike is on, then I get connection with E-tube app, but it stops me with an error and says remove incompatible unit SW-EN600-L
• I initially tested without the separate power button connected as I have read that the system can't have two units with power buttons, but as for testing, I tested both with and without.

Not sure if I'm missing something here. Any ideas?

I figured it out eventually...

I wrongly believed all EP6/EP801 used Gen2 systems, so I just searched up the SW-EN600-L and didn't take notice of the Gen1 vs Gen2 in the compability list. It turns out Gen2 is reserved for Shimano-batteries only, and all partner battery systems are on Gen1. I have a non-Shimano battery, and looking at the Gen1 compability list the SW-EN600-L is indeed not compatible.

This search to get bluetooth on my ebike has really made me hate Shimano ebike systems. I love their engines, but they are terrible at the compability and the lack of bluetooth. The only supported upgrade path from SC-5003 is the SC-EM800 (with SW-EM800-L) which cost around 400 euros only to get me bluetooth.
There are no sensible reasons why the SC-5003 doesn't have bluetooth support, or why the SW-EN600-L should not be compatible unless using Shimano only Gen2 system. These systems cost hundreds and hundreds of euros, and then they cheap out on bluetooth connection. I didn't even think to check it properly when I bought the bike as I took it for granted.

Why can't you use the ew-en100 to get Bluetooth and ANT+ on your Shimano Gen1 bikes?
