Can't turn Horizon Pro on

[madmic1314]

Hi all, found this earlier and been banging my head against a wall - grabbed by id using an iphone, but no matter what I put into EFR Connect or nRF Connect I can't get the projector to turn on. Wondered if anyone can help?

nRF Connect:
Company ID: 0x0046
Data: 0x46002b156feeb22440ffffff3043524b533d (as from my iphone, though the 2b15 section changes with each press)
UUID: 0x1812

I've got the same in EFR Connect as well - neither turns the projector on. I can see my phone on the iphone scanner only when advertising using nRF Connect

Any help much appreciated

Hi, did you check on the forum if somebody else was already successful with your projector? In the stack overflow thread you will find one case/projector where an additional scan code was required to turn the device on in case that might be maybe necessary for your model as well.

Thanks - I've looked over that thread and tried the various codes there, sniffing for mine gives me the above code. I tried sending the secondary code and still no dice. I can see the android phone broadcasting on the apple scanner. Weird as lots of others have made it work

Just to verify: Did you press the power button of your remote while the projector wasn't connected to electricity? This will make sure that the remote really sends the advertising code only.

Looking at the codes that have been reported so far I can recognize a pattern. All codes end with "ffffff3043524b544d". Yours has "33" in it instead of "44". Just an observation, don't know if this is of relevance. So the code part that varies from our collected list of codes is 14 characters after "0046".

Did you also compare with the EFR Connect BLE Mobile app for Android if the settings look the same as in this screenshot? Maybe you want to share a screenshot as well, just to double check.

[uni-uni-77](#5 (comment)) seems to have been successful with the same projector. Maybe you can reach out to this user.

Hope one of these suggestions helps.

Ok figured it out - late night fiddling yesterday meant I was putting too much data in by 2 bytes... oops!

460001156FEEB22440FFFFFF3043524B544D should be
01156FEEB22440FFFFFF3043524B544D

Tried it and it's working - amazing, thank you for your help!!

(the 533D was always 544D, just my tried brain mistyping)

Glad you figured it out!
