#25068) * Do not reset state if query image is not available (either not available, or protocol not supported or if delegate returns busy) * Update src/darwin/Framework/CHIP/MTROTAProviderDelegateBridge.mm Co-authored-by: Boris Zbarsky <[email protected]> * Addressed review comments * Update src/darwin/Framework/CHIP/MTROTAProviderDelegateBridge.mm Co-authored-by: Boris Zbarsky <[email protected]> * fix format specifier for nodeid and fabric index in the logs * Update src/darwin/Framework/CHIP/MTROTAProviderDelegateBridge.mm Co-authored-by: Carol Yang <[email protected]> * Fix style and bump up the default retry delay we communicate. --------- Co-authored-by: Boris Zbarsky <[email protected]> Co-authored-by: Carol Yang <[email protected]>
