What throughput should I expect for two BlueNRG-2's in SPI_DTM mode with DLE feature enabled?

2020-05-26
I have ported the BLE_Throughput_EXT example for two MCU/BlueNRG2(DTM) setups to communicate with each other. I was getting around 34 kbps. When I implemented this example on a single setup and configured it to send out Notifications when connected ...

Why does BLE_OTA_ServiceManager example in BlueNRG-1_2 DK 3.2.0 implement application level CRC?

Hello, I have configured a BlueNRG-M2SA as a network coprocessor using the provided DTM_SPI.hex file. I have connected it to an external uC and am able to read data from it. The problem is that as soon as the BlueNRG boots up and the interrupt is ena...

Having trouble flashing DTM image onto BlueNRG-2 using SWD/ST-Link V2

2020-04-01
I am trying to use the BlueNRG-2 Flashing Utility GUI to load the DTM_SPI.hex file onto the BlueNRG-2, but I am unable to flash or read anything from the BlueNRG-2's memory. The only result I get is "Waiting device to read". I am not using a BlueNRG ...

What MCU part number does the BlueNRG-2 use?

2020-03-25
I am trying to build new firmware for the BlueNRG-2 but am not sure how to configure it as a target. I have looked all over in the documentation and it just mentions that the BlueNRG-2 uses a cortex-M0 processor. I'm assuming it is in the STM32F0 fam...
