# *** UPDATE ***
Server now handles long reads and writes, still work to do on client.
This library is now ready with (mostly) all original BLE library compatiblity.
Check the examples and API_DIFFERENCES document for details of using this library.
3 simultaneous connections tested stable so far on both client and server.
NEW Client callback created - ```bool onConnParamsUpdateRequest(NimBLEClient* pClient, const ble_gap_upd_params* params)```
Called when the server wants to change the connection parameters, return true to accept them or false if not.
Check NimBLE_Client.ino example for a demonstration.
