Features• Restores FOTA functionality deleted by custom firmware.• Requires the following:

– STEVAL-MKSBOX1V1 (SensorTile.box) board– Mini USB B to USB-B cable– Micro USB-B to USB-B cable– ST-LINK/V2 programmer with correct driver installed on PC– STM32 ST-LINK Utility (STSW-LINK004) software installed on PC– Smartphone with ST BLE Sensor app installed– JTAG adapter board V1.0: adapter from JTAG20 to STDC14 connector– Flat cable to connect JTAG adapter to SensorTile.box– BLEFOTA_BL.bin firmware file

DescriptionThe STEVAL-MKSBOX1V1 (SensorTile.box) is a ready-to-use wireless IoT andwearable sensor box kit designed to help simplify app development based on remotemotion and environmental sensor data.

The kit firmware provides a range of development modes: from Entry Mode fordevelopers with little or no programming skills, to Pro Mode where users can loadcustom firmware on the SensorTile.box STM32 microcontroller.

The STSW-MKSBOX1_BL firmware allows you to restore the ability to upgradefirmware over the air (FOTA) in the event that FOTA functionality is overwritten ordeleted due to a custom firmware upload.

1 FOTA restore procedure

1.1 Connect the hardware

Step 1. Connect the JTAG adapter to the ST-LINK/V2 programmer and debugger.

Step 2. Connect the flat cable between the ST-LINK programmer/debugger and SensorTile.box.Pin 1 is labeled on both parts and should be connected with the cable pin 1 (black wire).

Step 3. Supply USB power (PC or wall charger) to the SensorTile.cox board via a microUSB-B cable.

Step 4. Connect the ST-LINK/V2 to the PC via USB cable.

Step 5. Select [Start].

Once the flashing procedure is complete, the SensorTile.box can receive the latest firmware available from ST viaa Bluetooth low energy connection with a smartphone.

1.3 Run the ST BLE Sensor smartphone app

You can perform this step after the BLEFOTA_BL.bin bootloader file is loaded on the SensorTile.box STM32microcontroller.
