BLE throughput under load, QOS

Hi Henry, I wonder if this could be related to the lack of buffers on the host, I assume you would use bt_gatt_notify with NULL conn which will take care of notifying each connection but that may end

Hi Carles, From these alternatives I only see 4 really working in practice, but it is limited to repositories being in github in which case the PR requests can perhaps be generated from a single clone

Hi Dhananjay, When you refer to subscribe I suppose you are talking about writes to CCC? Those are persistent if you have paired the device which I believe is mandatory in case of HID, clearing the su

FOTA takes so long to complete (MCUBoot + mcumgr + Bluetooth)
Hi Rodrigo, There are a few things that might help: 1. Increate the GATT MTU: We might need to increase the buffer size on Zephyr and then use Exchange MTU command to enable it. By default, it is set

[Zephyr-users] how to increase RX buffer of characteristic for BLE device
Hi, You should probably need to increase the MTU size, though both client and server have to agree on the MTU, also it is possible to that the app is using long write procedure so more bytes would fol

[Zephyr-users] Securing BLE device Services & Characteristics from unauthorized user
Hi Vikrant, You will have to add a service containing the characteristic which probably comes from a different application than the 'normal' mode, now regarding the AES key exchange I don't think that

BSD Sockets in mainline, and how that affects design decisions for the rest of IP stack (e.g. send MTU handling)
Hi Anas, Afaik a lot of ram is spent on buffers and if we can't do zero-copy that means at very least one extra buffer has to exist to move data around, fine-tuning the buffer size is also tricky espe
