Swing and a miss, sadly :baseball::x:

Itā€™s still giving me the rejection message. This is a rather infuriating problem to be sure.

my new working theory is that there is something that Iā€™m not doing. getting permissions or a message that i am not sending it in order to establish a proper connection. Is there something of the sort that a serial terminal uses to connect to a device?

something like whatā€™s described here:

Iā€™ve also learned that the Bluetooth device is actually bluetooth 5.1

First of all be sure the connection is established between your phone and the device.

The AT commands are all CAPITAL. serial ports donā€™t understand lower case by default.
ATZ is the reset command.

Try other UUID numbers such as 1101.

Some serial devices actually expects one letter at a time and ending it with a carriage return character.

Iā€™m not sure, the serial terminal app I used just let me type in the commands and send it through.

It used the notify uuid as the ā€œreadā€ one.

This bothers me so much, because Iā€™m starting to think itā€™s JUST thunkable thatā€™s not able to communicate properly with it.

Iā€™ll have to message the staff to find out if thunkable is capable of receiving from a notify uuid. Because I donā€™t know if The issue is me or the software at this point.

@domhnallohanlon is thunkable unable to receive data from a device that uses notify and not read?

Its Been Quite some time since Iā€™ve done anything on this project. with the new update, it should be a bit more possible, yet I am getting hit with ā€œopperation was rejectedā€ still,

Did this ever find resolve or a solution? I am working on something very similar although I have written the majority of my app in java / kotlin for android. I was not sure if there is a way to import existing code into thunkable - that would be a fine way to work around this type of thing. This is my first day looking at thunkable - i found it on trends.vc so I thought Iā€™d check it out. I used appinventor on google back in 2010 and 2011 - I had a moderate income from apps I created back then. tripadvisor took most of those customers after I got married and they became a ā€œthingā€ :slight_smile:

Anyways - hoping that you were able to sort out this issue - l think itā€™s likely the initial handshake with the bluetooth environment. I setup my bluetooth socket listener (adapter) a little bit differently than you do in your model. I couldnā€™t check out your project because I donā€™t have a pro account and I am not sure thatā€™s something Iā€™d be interested in if this service canā€™t perform better than my own coding - hoping it can take the nuances out of android app development and reduce the requirements for a team to a single person trying to make cool automotive apps. Thank you for your insight!
