Hi,I configure the BlueNRG-2N,On initialisation -> hci_reset -> hci_send_req ->after send_cmd the (!list_is_empty(&hciReadPktRxQueue)) is stell false and the timeout is reach i thing is something about pointing received data to the event list (or n...
I am trying to maximize throughput from a BlueNRG-2 chip to an android phone.The example code I have just spits out messages from the device to the phone as quickly as possible. Payload sizes up to 200 bytes (207 byte framesize) works OK, as seen bel...
I designed a USB-PD circuit using STUSB4500QTR. Circuit is error free and it shows the correct I2C address when I scanned using I2C scanner. But I can't able to configure the PDO profile using the STM32F072 nucleo board and GUI. I shared here the scr...
i am using st 232 evk bluenrg and serial_port_master_slave sdk 1. how to use this api and set the arguments i tries to filter some devices but unable to do so after setting the parameters the callback event ie hci_le_advertising_report_event dosent ...
I am interested in using the built-in 2.7V LDO on the STUSB4500 to power other parts of my circuit. Do you have any information on how much current this pin can source? And is the LDO hooked up to whatever VUSB is set to? For example, if the circuit ...
I see that all examples are for IAR or KEIL IDE.Can you provide CubeIDE projects as well?Regards,Piotr Romaniuk
(Please let me know the Parts ST26C31BN(4/0 Driver RS422, RS485 16-PDIP) is Active/Discontinued. )
Hi,I would like to know if L9637 transceiver can be used with LIN protocol.I would also like to know if this transceiver can be used in a system bus where there are many Electronic Control Units (ECUs) and their communication is through of K-line and...
Dear all.I am working together with a company facing a problem with TESEO-GNSS-Receiver in Japan. In an automotive usecase, with low SNR, the receiver gives us a wrong position, we've seen it off by up to 200 Meters. This alone would not be too bad, ...
Hi ,I am working on STM32L0 series controller with VD6283TX ALS on I2C interface.Though code is available for the sensor, my requirement is to write own code that will control the sensor. Sometimes it reads the RAW data from sensor and sometimes it ...
