error reading datafile
NadSo opened this issue · 28 comments
Hello,
I wanted to read a data file but I got the following error:
the file.txt is saved under the same directory where the bleah is
is file.txt in the folder where you're running the tool from?
file.txt is saved under: Desktop->bleah-master->bleah
you're running the tool from your home folder, give it the correct path of the file, how do you even expect it to work if you don't do that?! -.-
but that is what I did
no, your CWD is your home, so -r file.txt means -r /home/kamdem/file.txt which obviously does not exist .. learn to use a terminal please.
Is it supposed to do that?
I thought it would Read data to be written from the file.txt. Instead of it It just scan for BLE devices
There's a help menu and several examples in the README, you clearly didn't bother reading and understanding that documentation.
no it is not true. In the README the description says "Read data to be written from this file" . There is not any example about the datafile.
it can be any data
thanks yungtravla for your reply. But I thought the data in my file.txt should be read
? The grammar in the --help and README.md are correct, maybe you are misinterpreting?
Bleah reads the data - that will be written - from your text file
so it reads whatever contents from your file.txt and writes it to the UUID that you specify from a ble device
so for example if my file.txt contents the data: 1,2,3,4. the tool will write this data to the UUID ?
Have you tried --data? Then you will understand --datafile/-r
yes I did. --data is used to write some data to the characteristic
and yes.
bingo, and --datafile does the same, but reads the data from a file
In the same way --datafile/r is used the write data to characteristic from the file.txt, right?
that is exactly what I said and what is written in the docs.
wait. what...? Did you really just say it is used to write data to characteristics from the file.txt? Grammar plz
please explain to me what characteristics from a txt file are
Thank you so much. So by using --datafile I have to specify which characteristic I want to write data to. That is what was missing
I meant write data from the file to characteristics
try bleah -t10 -fe
wait 20 seconds, and bleah will enumerate all the characteristics
000fe00-000f-00f0-00f0-0000f00f0f0f00f these address types are UUIDs, you can write data to a UUID if it has the WRITE property listed next to it
Fixed by properly handling the exception:
