error reading datafile about bleah

[evilsocket]

is file.txt in the folder where you're running the tool from?

[NadSo]

file.txt is saved under: Desktop->bleah-master->bleah

[evilsocket]

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?! -.-

[NadSo]

but that is what I did

[evilsocket]

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.

[NadSo]

Is it supposed to do that?

[NadSo]

I thought it would Read data to be written from the file.txt. Instead of it It just scan for BLE devices

[evilsocket]

There's a help menu and several examples in the README, you clearly didn't bother reading and understanding that documentation.

[NadSo]

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.

[buffermet]

it can be any data

[NadSo]

thanks yungtravla for your reply. But I thought the data in my file.txt should be read

[buffermet]

? 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

[buffermet]

so it reads whatever contents from your file.txt and writes it to the UUID that you specify from a ble device

[NadSo]

so for example if my file.txt contents the data: 1,2,3,4. the tool will write this data to the UUID ?

[buffermet]

Have you tried --data? Then you will understand --datafile/-r

[NadSo]

yes I did. --data is used to write some data to the characteristic

[buffermet]

and yes.

[buffermet]

bingo, and --datafile does the same, but reads the data from a file

[NadSo]

In the same way --datafile/r is used the write data to characteristic from the file.txt, right?

[buffermet]

that is exactly what I said and what is written in the docs.

[buffermet]

wait. what...? Did you really just say it is used to write data to characteristics from the file.txt? Grammar plz

[buffermet]

please explain to me what characteristics from a txt file are

[NadSo]

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

[NadSo]

I meant write data from the file to characteristics

[buffermet]

try bleah -t10 -fe

[buffermet]

wait 20 seconds, and bleah will enumerate all the characteristics

[buffermet]

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

[evilsocket]

Fixed by properly handling the exception:
