No advertisments from NUCLEO-WB55RG

[Thomas L.]

Hi

I recently received a NUCLEO-WB55RG (the big board, not the USB dongle) and tried installing the demo from the STM32CubeWB repository.

I saw that I need to flash the FUS + Stack first which I did. STM32CubeProg reports 

• FUS State: FUS_IDLE
• FUS Status: FUS_NO_ERROR
• FUS Version: V2.2.0.0
• STACK Version: V1.24.0.3
• STACK Address: 0x80D0000
• FUS Operator: v3.1.0

The files I flashed were:

• STM32CubeWB-master\Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x\stm32wb5x_BLE_Stack_full_fw.bin
• STM32CubeWB-master\Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x\stm32wb5x_FUS_fw.bin

As application I chose the p2pServer application

• STM32CubeWB-master\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_p2pServer\Binary\BLE_p2pServer_reference.hex

When I disconnect the SWD Interface and press the reset button I get the following output (nothing else):

Wireless Firmware version 1.24.0
Wireless Firmware build 3
FUS version 2.2.0
>>== SHCI_SUB_EVT_CODE_READY
>>== SHCI_SUB_EVT_CODE_READY - FUS_FW_RUNNING

Now I assumed this should be enough to at least see the device advertising.

But none of my applications can see the device. I tried the following apps:

• ST BLE Sensor
• SiConnect (Silabs)
• nRF Connect (nRF)

I do not get a single indication that the device is alive.

What am I missing?

Did I mention that when I try to build the example it doesn't compile out of the box?

Well, apparently you need to explicitly push the "Start Stack" button and then upload your application. I thought I had done that before but the correct update routing was:

1. Update FUS
2. Update Stack
3. Push the Start Stack button
4. Upload your binary

I have to somewhat admit that this is a horrible experience for a first bringup.
