I want to upgrade the WB05N chip on my custom board.
I downloaded X-CUBE-WB05N v2.0.0 and programmed the chip with BLE_TransparentMode_SPI_with_Updater.hex (I am using SPI on my board).
I selected the Verify and Run after programming options. The download verified successfully, but when I call hci_reset() I get a timeout.
Additionally, when I compare the BLE_TransparentMode_SPI_with_Updater.hex file with the image read back from the module, there are differences.
With version 1.0.0 everything works fine (image comparison is identical).
Do you have any ideas what might be wrong?
