Hi @MKind , if you are not using the ST.box long time, you need first of all to plug it via USB to allow the battery charging. Then you have to check the BLE connectivity between your ST.box and your smartphone (btw, is your smartphone a Huawei phone?). The connection is ON if the blue led blinks.
But how did you exactly uploaded the FW? In case of no recent upgrade, when you open the app and detect the ST.box device via BLE, the FW will be automatically downloaded. But this is not the case, I suppose. So you can follow the below instructions to upload a default .dfu file in .dfu mode (no need of ST link V2 or V3 utility):
- install DfuSe utility (STSW-STM32080 package), if not already done (please follow the first section of the UM0412 for the description of the dfu mode)
- create a dfu file e.g. from the .bin file BLESensors.bin in \en.FP-SNS-STBOX1_firmware\STM32CubeFunctionPack_STBOX1_V1.0.0\Projects\STM32L4R9ZI-SensorTile.box\Applications\BLESensors\Binary. You have to use the DFU File Manager installed together with the DfuSe tool. Please follow p.16 instruction of the UM0412.
- remove the ST.box package, if not yet done
- unplug the battery from the ST.box, if plugged
- press the BOOT button and plug it to your PC via USB cable while keeping the button pressed
- release the BOOT button once the USB is plugged
- open the DfuseDemo app and check if your device is recognized
- if the device is detected, upload the .dfu file created at point 2 (please follow the User interface part of UM0412 for the description of the dfu mode)
- once the FW has been upgraded, release the .dfu mode
Regards
