How to get 'gatttool' command to work

[FFont.1]

Hi,

I'm working with the stm32mp157f-dk2 and with OpenSTLinux and I'm trying to create a GATT service for provisioning the wifi credentials.

The problem is, according to https://wiki.st.com/stm32mpu/wiki/How_to_scan_BLE_devices I should be able to run the gatttool command. Unfurntently I'm not.

I have already re-flashed the OpenSTLinux and I also have reprogrammed the kernel.

I'm running the OpenSTLinux 5-4 20-11-12.

What should I do? I have also tried the apt-get install command..

Thanks,

Fernando Fontes

Hi @FFont.1​ ,

I understand Gattool is provided by gattlib module.

Is it the one you tried to app-get ?
