 ## Methods
 
-#### bluetooth.init(id=0, mode=Bluetooth.BLE, antenna=None)
+#### bluetooth.init(id=0, mode=Bluetooth.BLE, antenna=None, modem\_sleep=True)
 
 * `id` Only one Bluetooth peripheral available so must always be 0
 * `mode` currently the only supported mode is `Bluetooth.BLE`
+* `modem_sleep` Enables or Disables BLE modem sleep, Disable modem sleep as a workaround when having Crashes due to flash cache being disabled, as this prevents BLE task saving data in external RAM while accesing external flash for R/W
 * `antenna` selects between the internal and the external antenna. Can be either
 
   `Bluetooth.INT_ANT`, `Bluetooth.EXT_ANT`.
