The Lis2du12 chip is malfunctioning, and the ODR of the CTRL5 register can only be written to 0x4 and 0x8. When writing to 0xa and then reading, it is 0x8, and the register status is always 0x02, and the power down bit is always 1, indicating no oper...
Hello,I am using BlueNRG-M0A and have a successful implementation working. However, I have a scenario that I'm unsure how to properly program.If I am currently paired to a Bluetooth device (i.e. a phone). The Bluetooth app crashes or the phone goes o...
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,
