Hi,

Thanks for providing the details. I saw that there were fixes to GATT in 5.49 but I am not sure what these are. Maybe you could try to ask a question on the Bluez Mailing List?

I thought so after trying with my phone (which has no problems reading the data). After searching the web for ages i found: hcitool and gatttool no longer distributed with standard BlueZ packages

One has to use btmgmt now which is in the bluez packet. The newest packet (right now 5.49) can be downloaded at bluez.org

This help for using btmgmt is also displayed in the console. But i did not manage to connect to the Thingy yet.

Before calling this tool a "sudo rfkill unblock all" is needed.
bgmgmt has to be opened as sudo
Make sure BLE is on (Call "power on" and "le on") and connectable ("connectable on")
use "find" to scan for devices --> list with MACs and RSSIs is displayed
try pair [MACofThingy] and receiver a 0x04 error (connect failed).

FAIL - I have to work some more on this problem. Not beeing able to connect bugs me.

Hi,

This is likely an issue with your BLE drivers on Linux and not the Thingy:52 itself. See if you can connect to any other BLE devices. If not, you should do an update (or possibly rollback) of your BLE driver.

We have have an example of Thingy:52 and Raspberry Pi using Raspbian Jessie which might be helpful.
