BLE SMP

Meshtech devices utilizing Nordic's nRF Connect SDK (NCS) use BLE SMP protocol instead of Nordic DFU. This eliminates the need to switch them to a separate mode to perform upgrade. Simply connect with the BLE SMP host and send the upgrade.

BLE SMP with App

This is how to upgrade a Minew MBM01 0043 using nRF Connect for Mobile. Procedure will be very similar for all Meshtech devices supporting BLE SMP.

Note

Devices operating in Connected mode currently connected to a network will not be discoverable while scanning with nRF Connect app. To discover and connect to a Connected mode device either switch device mode from system by writing property 0x8110 - Device Mode, move it out of range of network, or power off gateway while doing the upgrade.

  • Scan for and connect to the device you want to upgrade. RSSI filter is a convenient way to find the device near your phone.
  • Select the device you want to upgrade and click Connect.
  • Click the DFU icon to open a prompt where you can select .zip file to upload.
  • Navigate to the appropriate .zip file you want to upgrade to and select it to start upgrade.
  • Upgrade will now proceed, showing a progress bar and notifying you when upgrade is complete.

Note

Video instruction shows nRF Connect for Mobile running on Android device. iOS version is also available and is similar, but will not show MAC address.
