The gatt discovery proceedure simplification to discover all characteristics at once has exposed a device side issue where some device implementation reports orphaned characteristics. While this technically shouldn't be allowed, some instances of this were observed (namely on some Android phones). The fix is to simply skip over orphaned characteristics and continue with everything else that is valid. This has been tested as part of the Android CTS tests against an affected platform and was confirmed to have worked around the issue. --- src/shared/gatt-client.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/shared/gatt-client.c b/src/shared/gatt-client.c index 963ad619f..d604c77a3 100644 --- a/src/shared/gatt-client.c +++ b/src/shared/gatt-client.c @@ -632,7 +632,10 @@ static bool discover_descs(struct discovery_op *op, bool *discovering) util_debug(client->debug_callback, client->debug_data, "Failed to insert characteristic at 0x%04x", chrc_data->value_handle); - goto failed; + + /* Skip over invalid characteristic */ + free(chrc_data); + continue; } if (gatt_db_attribute_get_handle(attr) != -- 2.26.2.526.g744177e7f7-goog
