Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Is there more documentation somewhere for the BlueNRG GUI Script Utility commands? There is just a table in document UM2058 with very little detail. One has to guess and use the error messages from Python to try to figure out the command parameters...
Hello,I have a few questions regarding the use of the BlueNRG-2 deviceI am building a system where I have to send small data packets (10 bytes) from 1 unit to 10+ units. I am aware that you can only have 7 simultaneous connections, but I am wondering...
Hello,we would like to add a charge functionality via USB PD for an USB hub. Charging should be possible for the upstream port, e.g. the host shall be charged. The tricky part is, that the charge process has to be activated and deactivated during run...
Good morning, I am working with a nucleo-l476RG board and the expansion board x-nucleo-idw01m1. I'd like to know where can I find the image to flash on the SPWF01SA through the FW upgrading over UART example.ThanksCarlo Delbono
Title somewhat covers it,I have a custom circuit based off the Blue Tile eval kit BCN002V1 board. I'm trying to flash it with the host board and the BLE_SensorDemo.hex but I'm not seeing the board pop up in the comm ports when I connect it like I wou...
Hello Support,We selected the following TPM to design into a new product and chose the ST33HTPH20xxAHC3 part for the design. The product is a specialized Android tablet that is mounted outside conference rooms for room scheduling. We are now entering...
I am trying to do a file transfer over ble, using 20 byte characteristics writes. I did notice that, following a write command for characteristic, the resultant aci_gatt_attribute_modified_event() doesnt get called quick enough to process the next in...
I've been trying for some time now to get my F767ZI writing to an ILI9341 8080 LCD.The equations detailed in the AN2790 datasheet:(1) DATASET*tHCLK = tWP(2) ((ADDSET+1) + (DATASET+1))*tHCLK >= MAX(tWC)(3) DATASET >= ((tAVQV + tsu(Data_NE) + tv(A_NE))...
I am developing a custom board in which I want to interface a BLE chip and for that, I am looking forward to using BlueNRG-2 in my design. From what I have studied online BlueNRG chips support only SPI based interface with the Host controller. The pr...
