Hello everyone,I'm trying to write a driver for the ILI9341 display (8 bit parallel mode, not SPI) using the ST HAL. I couldn't get the libraries I found online working, I imagine for the same reason I can't get mine to work. Obviously I have double ...
Hi,I am doing simulations for Electrical Characteristics and find the the IDSS and IGSS are in the range of nA instead of uA as quoted in the datasheet. Can any ST Engineer help me if the numbers need updates? I filed a support ticket, instead was in...
According to the characteristic/features section in this BlueSTSDK documentation page, characteristic data has a 2-byte timestamp. What are the units of this timestamp? In other words, what does each tick in the timestamp represent? The timestamp goe...
Hello,i defined a characteristic with notify propriety : ret = aci_gatt_add_char(Service2_Handle1,UUID_TYPE_128,&char_uuid,26,CHAR_PROP_NOTIFY | CHAR_PROP_WRITE | CHAR_PROP_WRITE_WITHOUT_RESP,ATTR_PERMISSION_NONE,GATT_NOTIFY_ATTRIBUTE_WRITE | GATT_N...
It looks like BlueNRG-MS doesn't remember that BLE client asked it to change CCCD from 0 (default value) to 1 (subscribe to value change notifications) upon BLE server reboot. And I need to restore CCCD to 1 because BLE client doesn't do it on reconn...
Hello,How can i modify the configuration of Generic Access (0x1800)e and Generic Attribute (0x1801) services ?add characteristic and change permissionsplease find in attachment actual configuration (by default) and the target configThank you,
Hi I using bluenrg2 m2sp chip as pheripheral role and st ble sensor App as a Central , i need to sent notification from peripheral to Central whenever event occur , con you share information , which api i need to use in order to sent notificatio...
Dear SupporterWe make a design using the "VL53L1X" for people counting applications.To test it, we placed it above the entrance of a room (as in the YouTube link "People Counting Using a Single ST Time-of-Flight Sensor" posted by ST Microelectronics)...
Hello Everyone,I have issues communicating with my new Nucleo-G431RB using usb driver STSW-LINK009 in win10. Here is what I found. After plugging in the use cable to my laptop, I saw an "unknow USB device (Device description request failed)" showed...
Hello,I have configured the BLE Beacon V1.0 sensor with the Nano Beacon software, I can detect it with applications like nrf Connect or ST BLE Toolbox. I've programmed a stm32 card as a client, I can detect the devices, but I can't detect the beacon ...
