Hello everyone. I'm facing a issue when I try to use CODED_PHY instead 1M_PHY. When I start a GAP_GENERAL_DISCOVERY_PROC, the stack returns: 0xD1 (BLE_STATUS_INVALID_SCAN_CONFIGURATION).Could anyone help me? The scan configuration is (return 0x00 - O...
Hello,I have implemented test functions gci_le_transmitter_test() and hci_le_receiver_test() in our firmware for tests in lab. We have setup a test bench with one hand our product and on the other hand a STEVAL-IDB008V2 driven by BNRGUI software.We h...
Using the STEVAL-LNBH06 I am not able to achieve 93% efficiency as stated in the data sheet. Please advise why this might be.inout voltage: 12Vload: 43ohm power resistor for each channel (draw 420mA per channel)measured input power: 20.4Woutput power...
Hello Everyone!I think it's a weird question, however, I am new to NUCLEO-H743ZI2. Actually, I am facing the issue of low-speed data transfer from MCU to PC (LabVIEW). Before, I was using programming and debugging USB ports to transfer data to LabVI...
Hi team,Is there any transceiver that has 2 channels and is ISO14230 or ISO9141 compatible? The most important is that this transceiver must supports 24 V in VBB pin (vehicle batery). Also is important that there is a level changer internally.
Hello,to reply to your request of information: "One open question for you, what kind of antenna do you plan to use to cover both 433 and 868MHz with a single antenna matching circuitry ?"I attach a picture of the antenna vertical sleeve @ lampda/4 wh...
Hello. ST team.i'm using L9369's voltage measurement function.i read L9369 manual, and i send below SPI commands(no.0~6) for initial driving.(my purpose is to drive FET : HS1 A, B ON / LS2 A,B ON)00xb5019ff810xb5a15fef20xb720b54d30xb480aa9840x40a0000...
Hello, I measure the output differential voltage of the drivers (with 100ohm termination resistor) and it is always higher than 0.4V that is referred to the datasheet. What I measure is about 0.68V. Is that normal? Thank you in advance
Good afternoon, We are evaluating the possible consequence for the LVDS transceiver RHFLVDSR2D2 in case that it is supplied with a voltage above its absolute value which is 4,8V.In particular we are asked to evaluate the case that voltage applied to ...
Hello to everyone. I am trying to see the data via I2C with the capacitive sensor (FDC2214-Q1),but I see the values I have assigned as 0 in live experiment.I'm sure about the hardware part. I would be happy if you help. /* Private define -----------...
