Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
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 ...
I'm starting a project with BLUENRG-LP and I used WiSE Studio to map the pins and generate the initial project. On my board, I have an LED connected to a GPIO pin I would like to blink, so I added to the while loop:HAL_GPIO_TogglePin(GPIOA, LL_GPIO_P...
Hello, recently I desoldered a STMicroelectronics B2L334 from a dead power supply of a dell dimension 2400, but i cannot find a datasheet on it. Does anyone have the datasheet? I need it. Thanks.
