Node-Red on Android for Free

[@highvis_supply]

apart from the less than stellar sensor access, I ran this on a sony xperia xz premium and nodes installed just as quick as a raspberry pi, not to mention I had 100hz IMU data going through it with no lag. Not sure why its so slow on your end, it seems unreasonable even if the phone isn't top end

[@AnotherMaker]

That phone was old and this was about a year ago, so I'm sure things have improved a bit.

[@diegoteceletro]

man, you helped me so much. thank you!

[@AnotherMaker]

Happy to help! Thanks for watching!

Hi, thanks for putting up your experience. One specific question regarding the phone sensors access. Did you find any of the two approaches - the app versus native install better in terms of response times and jitter from fast sensors like acceelerometer?

[@AnotherMaker]

That's a really good question. I don't think I noticed any difference. Since neither approach uses root access, I would expect them to be pretty much the same.

[@ashishplatinum]

@@AnotherMaker thanks ! I am building a project to use the phone as a gateway, to fetch readings from BLE sensors, so far haven't found a way. I tried installing BTLEWRAP and Bluez package but didnt work. Ever tried ?

Hi, if you try the command for the camera from the exec node as they tell you a the API page it does the photo and you can find it at *cd* from Termux, although I haven't figured out yet how to display it.

[@AnotherMaker]

Ohhhhh. Very cool. Thanks for sharing. I will give it a shot. It's kind of funny as a software developer exec is generally one of the most dangerous commands you can use and people try to avoid it at all costs

[@cardansan]

@@AnotherMaker Sure, pal. That's funny, I've had to use it multiple times to acces specific things on Raspberrys but maybe since I always have backups of the images on PC or the flows with Projects I've lost the fear of it, plus I read they had used only exec nodes prior to the Termux API ones because they were made afterwards or something, and assumed it was safe.

[@AnotherMaker]

@@cardansan Interesting. Yeah. In general I believe exec allows you to directly run commands at the permission level of the application. So that's why people freak if you do sudo node-red instead of node-red because of the vulnerabilities, etc. I use it from time to time though.

[@milian5934]

Very cool, I just bought the Loomo Segway, I would love to use Node Red to code it since it is Android base. Is there a place where I can learn how to add their SDK to Node Red? It will be great to have their SDK as nodes.

[@AnotherMaker]

I'm not sure off the top of my head, but I'm working on that sort of thing. Currently turning a motorized wheelchair into a robot.

You can find the IP address of the phone by going to Settings -> About phone -> Status.

[@AnotherMaker]

Good call! Thanks!

with Peter Scargill we adapted his script to run on a smartphone a couple of years ago, all details in next comment :)

[@AnotherMaker]

That is fantastic. I can't wait to check it out

[@squalazzo]

@@AnotherMaker it was not updated since then, so don't know if that still works

[@AnotherMaker]

@@squalazzo I'll give it a shot!

[@cristimihai8472]

How do i secure it?

[@AnotherMaker]

The termux version should secure like any other NR install. nodered.org/docs/user-guide/runtime/securing-node-red

[@testuser2709]

Termux is proot - it’s always going to be slower than native

[@AnotherMaker]

Absolutely. I'm just amazed it works at all
