Dear all. I stumbled across something I don't really understand. I'm trying to detect a signal using SPI1 on STM32f723 as fast as possible and fill a buffer. I configured SPI1 in SPI_DIRECTION_2LINES_RXONLY mode, set prescaler to SPI_BAUDRATEPRESCALE...
Dear all I have terrible problem regarding security in my application developed for a client. I am using BlueNRG-2 in my target system (which is custom made) and I observed the same situation on STEVAL-IDB007V1 as well. To make things short, the ea...

Hi all.
I noticed that when debugging a STM32F091 MCU my systick ISR never gets called. I Use STMCube library, so HAL_GetTick and HAL_Delay ceases to work as well (because uwTick is not increased). But onl...
Posted on April 15, 2016 at 00:13Hi I think I found a bug in aci_att_find_information_req which always returns BLE_STATUS_TIMEOUT for me. This function creates a hci_request variable, fills it with zeros, and then sets all fields except ''event''...
Thanks everybody! I think TDK got it right! I added __HAL_DMA_DISABLE (hdma); in SPI_DMAReceiveCplt and set a breakpoint just after disabling the DMA and everything works smoothly now. I see all 0xf0 values even with circullar mode. The problem is th...
> How do you output and check data? Debugger or UART? Both might be bottlenecks for data throughput, not only if not copied to an extra output buffer.I stop on a break point and check the memory (1024B buffer). I did that after a delay and in an rx-c...
Thanks guys.> "What are the exact values you're receiving and why do you think they're off?"In DMA_NORMAL, with SPI1 running at 54MHz, and function gen. feeding 6.75Mhz square (6.75 == 54/8) i get:As you can see we get 1e, 1e, 1e which in binary look...
It indeed were problems with privacy. I made small article on how I fixed this in case someone was interested : http://www.iwasz.pl/electronics/bluenrg-2-android-source-code-troubleshooting-bonding-and-privacy/
Hey guys, As suggested somewhere else on this forums It seems, that both iOS and Android Lollipop and higher uses Random Private Resolvalble addresses (http://www.summitdata.com/blog/overview-addressing-privacy-lairds-ble-modules/), so this would ex...
