   Thanks @btashton! PineDio Stack BL604 fails my LoRaWAN Network Test because it couldn't receive any LoRaWAN Packets (Join Accept Response). Sending LoRaWAN Packets is OK. I traced it to this commit: https://github.com/apache/incubator-nuttx/commit/4dbf4555ebb743a908e3016d43b5b456d7a2cf16
   
   The LoRaWAN Test calls my [LoRaWAN Library](https://github.com/lupyuen/LoRaMac-node-nuttx), which calls my [Semtech SX1262 Library](https://github.com/lupyuen/lora-sx1262/tree/lorawan), which calls the [NimBLE Porting Layer](https://github.com/lupyuen/nimble-porting-nuttx) (for multithreading functions).
   
   Since the commit https://github.com/apache/incubator-nuttx/commit/4dbf4555ebb743a908e3016d43b5b456d7a2cf16 has to do with File System, maybe something inside NimBLE Porting Layer broke.
   
   I plan to trace the calls to [`dir_open`](https://github.com/apache/incubator-nuttx/blob/master/fs/vfs/fs_dir.c#L397-L402), [`dir_ioctl`](https://github.com/apache/incubator-nuttx/blob/master/fs/vfs/fs_dir.c#L548-L560) and [`dir_allocate`](https://github.com/apache/incubator-nuttx/blob/master/fs/vfs/fs_dir.c#L566-L608) to see what changed.
   
   The weird thing about this bug: LoRaWAN works perfectly fine on PineCone BL602, only PineDio Stack BL604 is affected. (Maybe due to the different drivers and apps loaded in memory?)
