Bluetooth file transfer on stm32mp157

[adnan_pasha]

Hi,

I’m working with the STM32MP157DAC and using the Mickledore BSP distribution to build a custom image.

Our design includes a Wi-Fi + Bluetooth combo module based on the IW611 + 88W8987 chipset.

We've successfully established Bluetooth connections—streaming audio from the STM32MP157 board to Bluetooth headphones, and from a mobile device to the STM32 board.

Now, we're looking to transfer files via Bluetooth from the STM32MP157 to a Linux or Windows PC.

Could you please advise on how we can enable and implement Bluetooth file transfers (e.g., via OBEX or similar)? Any guidance or recommendations would be appreciated.

Thanks

Hi @Olivier GALLIEN 

I was able to successfully transfer files from the STM device to both an Ubuntu laptop and a mobile phone using the obexd daemon.

However, I'm facing issues when trying to send files from the mobile or laptop to the STM device:

• On the mobile device, the STM board does not appear in the list of available devices for file transfer, even though it is paired and connected via Bluetooth, and can receive files from the STM device.

• On the Ubuntu laptop, attempting to send a file results in an error stating "Unable to send file. Make sure Bluetooth is turned on or connected", even though the connection is active and the laptop can successfully receive files from the STM device.

It seems that while outbound transfers from the STM device work fine, inbound transfers are not being detected or accepted.

Any guidance on resolving this would be appreciated.

Regards,
Adnan
