Does the FCC require the 2440 MHz band to be tested, too? FCC response on 11/19/2025 Thank you for your inquiry. Please provide additional context for your question. What channels/frequencies can this device transmit for BLE? Is it only the advertising channels (37, 38, 39)? ---Reply from Customer on 11/25/2025--- Good morning, The Sentinel Flex can only transmit onthe advertising channels. That s channel 37, 38 and 39. Thank you. FCC response on 11/25/2025 Thank you for the clarification - it would be acceptable to omit 2440MHz as a test channel as the device does not operate on that frequency.
