Hi Kevin @DTS Engineer, Thanks for the detailed answer. We've filed the report as FB25214517. In short, we're suggesting that when Wi-Fi is off and there's only a single BLE connection, the connection event be allowed to use more of the interval, since the coexistence and radio-sharing constraints wouldn't apply in that case. Thanks again for passing it along to the engineering team, and we hope to hear from you soon with possible resolution! @7_strikes when it comes to the L2CAP channels, we have tested this with the custom firmware, and the result is pretty much the same. GATT only introduces a couple of percent of overhead when it comes to the sheer number of bytes you can pass through, at least at the load we need it to work. The problem stems from the airtime, and not the protocol used.
