Newer USB cables should be backwards compatible, so you should be fine as long as the USB plugs into the GHL.
I have no way of making a connection through the app since it's not on my new WiFi yet & the default wifi hotspot does not work since it was on my previous house network. When I plug in the USB-C end into my computer it does not recognize the doser.
did you ever figure this out? im currently trying to connect my 2.1
Nope, which is why I sold the doser. I absolutely love GHL equipment, it is well made and will last a long time, but I can not stand sh**** software that forces you to use a PC to do any firmware updates. No manufacturer should require you to use a specific computer to do anything, which is why I'll never use GHL until they change this. I asked them about being able to use Macs in the future and the person who responded pretty much said they would never use an Apple product, which seemed more like a personal issue than anything else. I also hated their app or browser software, it was slow, unresponsive and generally from the 80's. I still don't understand why manufacturers charge a premium for a product and spend little to nothing on software developments? I think this applies to 90% of manufacturers in this hobby. Okay, stepping off my soapbox.
