Description
On Microchip RN4870 devices, when more than one consecutive PairReqNoInputNoOutput request is
received, the device becomes incapable of completing the pairing
process. A third party can inject a second PairReqNoInputNoOutput request
just after a real one, causing the pair request to be blocked.
