* Use enum class for TLVElementType and TLVTagControl. This makes it easy to give them as specific size spec, which will prevent issues with people adding out-of-range values and simplify -Wconversion work. * Check if the result of EncodeCommand is successful before trying to send the command (#3151) * Remove verbose code comments (#3187) Some devices are configured to act as Thread router instead of sleepy-end device. This PR removes these incorrect or verbose comments. * Remove {#mainpage} from the main README.md file (#3190) * Remove Makefiles introduced by #3099 (#3191) * [nRF Connect] README updates on Docker for MacOS and NCS version (#3175) * [nRF Connect] README updates on Docker for MacOS and NCS version * Restyled by prettier-markdown * Rephrase a sentence Co-authored-by: Restyled.io <commits@restyled.io> * Modify the generated files for example lighting and lock apps to include server init callbacks. (#3180) This allows the app to implement emberAfPluginOnOffClusterServerPostInitCallback to sync up the data model state with the state of the actual device when the data model initializes. * Use pragma once in more places (#3182) * Add a lot of pragma once changes. Now scripted! * update pragma once in setup payload * More pragma once * Pragma once within platform and more * pragma once in the crypto layer * pragma once in examples * Fix by restyle-diff * [android] Use ATT Write Request instead of ATT Write Command (#3161) Co-authored-by: Vivien Nicolas <vnicolas@apple.com> Co-authored-by: Yakun Xu <xyk@google.com> Co-authored-by: Damian Królik <66667989+Damian-Nordic@users.noreply.github.com> Co-authored-by: Restyled.io <commits@restyled.io> Co-authored-by: Andrei Litvin <andrei@andy314.com> Co-authored-by: Łukasz Duda <lukasz.duda@nordicsemi.no>

Problem
Whenever CHIP Tool for Android writes to the characteristic it does not request acknowledgement on ATT layer.
This violates the current CHIPoBLE specification (section 4.7.3.2, visualization in figure 5).
