Hi, just wanted to chime in here, since we are experiencing similar issues as the OP. We have also developed an app that uses 2 BLE peripherals that stream data simultaneously at a high frequency. From our logs we can see the in field performance of a wide variety of models from hundreds of iPads used by customers around the world and we noticed customers using the iPad A16 11th gen Wi-Fi only (iPad15,7) model have been experiencing Bluetooth related issues. The issues have been observed since it's release (March 2025) and across a variety of iPadOS versions (from 18.3 up to 26.3). We have not seen these issues with customers using the iPad A16 11th gen Wi-Fi + Cellular (iPad15,8) and other models. We have since acquired this specific model (iPad A16 11th gen Wi-Fi only) for internal testing and we consistently see - even while using iPadOS 26.3.1 - around a 1 second delay in the data for 1 of the connected peripherals. Hopefully a resolution can be provided in the near future, since it severely impacts our customers using this specific iPad model.
