Hi,I'm trying to send 32 bit data with DMA over SPI to a slave device with the STM32WB55 which can only be configured to use hardware NSS with 16 bit transfers at most. I understand that I will likely have to pull the chip select down manually, send ...

Hi,I am running the BLE_DataThroughput example for the STM32WB55 with two boards as described in the documentation- one set as a client, one as a server. I have connected the client board to a desktop PC via UART, and I am monitoring the output with ...

Hi Robert,This is an interesting setup, thanks for showing it. I could not make the 2 nucleos to transmit at more than 90 kBytes/s unfortunately. For the record, I made sure to have the latest FUS and the full BLE stack flashed on them as per the ins...

Hi Robert,Thanks for your persistent help. I imported your project as is and I am still getting the same throughput~ 90 kBytes/s. I am wondering whether it might have to do something with the fact that I am using 2 separate nucleo boards to run this....

Hi,First, thank you for replying! I have tried these configurations of #define CFG_TX_PHY 2#define CFG_RX_PHY 2and changing the CONN_P1_400 and CONN_P2_400 to CONN_P2_50 and CONN_P2_50 but unfortunately, I was unable to get such a good result. I al...

Hi,No, unfortunately, I do not have an answer yet. I will post here if I find a working solution. Please do the same if you come up with one first. Meanwhile I am looking at Nordic Semiconductors' forums as it seems they offer better support and more...

What is the fastest way to manage slave select manually when trying to send 32 bit data over 16 bit SPI with DMA (STM32WB55)?

How do I achieve the advertised 2 Mbit/s (or close to that) data rate on STM32WB55 with the BLE_DataThroughput example?
