I am communicating with the BlueNRG-MS over SPI using an ST eval board with an F1 micro. I am able to send data over the MOSI line and receive the 0x2 ready data as shown in the attached image. I am having issues with receiving data from the BlueNRG-MS device.
When I send a read command in the header, I only get the 0x2 on the MISO line.
Does the BlueNRG-MS component need a certain firmware loaded to enable it to set the IRQ line high when it has data to send? It is currently running with v7.2c. (details also attached below)
I am curious to know how the IRQ line is set high.
