Cannot increase handle count and have characteristics with both and Read and Write on BLE_Gateway example. #55

Has the latest change removed the previous features of adding handles and having both read and write capability on each handle? If it is changed, please, suggest a way how to get the old feature back.

Yeah, this comes down to the new cache solution. The read operation is still available, but you'll risk getting the NRF_ERROR_NOT_FOUND if it's not in the cache.

If you want to mitigate this, you have two options:

  1. Increase your cache size by changing the RBC_MESH_DATA_CACHE_ENTRIES #define.
  2. Mark some handles as "persistent", meaning that they will never be flushed from the cache. If you have assigned a few selected handles to each device, this is the best option.

If you have a cache size larger than the range of handles you're using, the behavior will be exactly as before.

Can you please point me to the specific of this cache solution? Is this change applicable to the whole mesh service?

Got the explanations on the release notes. Should have looked at there first. My bad. :)
