+ | ===== What to do when the enddevice has the status "Data Up mic error" with the value "Exceed FcntUp max gap" ? ===== | ||
+ | |||
+ | This message indicates that there is a too large gap between the previous FCountUp counter value and the new counter value. \\ | ||
+ | That may happen when the gateway that was transferring the LoRa messages to the WMC server has been switched off a long time. \\ | ||
+ | |||
+ | To fix this issue: \\ | ||
+ | |||
+ | **1/ Reset the enddevice** \\ | ||
+ | Normally the enddevice should rejoin the LoRa network and counter will restart from 0 after the join procedure. \\ | ||
+ | |||
+ | If this operation does not fix the issue: \\ | ||
+ | |||
+ | **2/ Remove the end-device definition from the WMC dahsboard (de-provisioning) and re-create it (re-provisioning) then reset the end-device.** \\ | ||
+ | This last operation should make the enddevice recommunicating with the WMC server (LNS). | ||
