We use STM32L162xx MCU to communicate with S2_LP and SP_BTLE drivers via SPI. With S2-LP, it returns the MC_STATE as READY during inital setup for power , sync word etc. But when I Strobe the RX command it returns MC_STATE as LOCK_ST(0x14). DMA is...
Hello,I was researching ST eSIM offerings, and what I found out is that SIM provisioning goes through partner 1Global. My primary use case is to be able to provision the eSIM with multiple profiles without using 3rd party.Can you please tell me are t...
I am using STM32L34 with STPM34, where I am trying to disable CRC once the power up sequence is done ( global reset),but STPM34 chip always sends row 0 values. can anyone tell me what could be the issue? I am also attaching SPI bus data.
Hi,I am using a SIM7080G module along with the eSIM model ST4SI2M0020TPIFW, and when I use the AT+CCID or AT+CPIN? commands, the module responds with "+CPIN: NOT INSERTED". I have followed all the steps in this tutorial to activate it, and I managed ...
Dear all, Im currently using STSW-IOL4LSV1 package for evaluation.My Company has no IO-Link venodor ID, based on IO-Link regulations we are allowed to develop devices for ourself even without it but we dont want to use our old Stack anymore. I cannot...
Hello,I'm using BALF-SPI2-02D3 with the S2-LP chip at 433MHz.However, my application is only for reception, and no RF transmission. What should I do with the Tx pin on the Balun? Open, Resistor to GND or Capacitor to GND?I also need the same answer f...
Hello everybody.I have a STEVAL-FCU001V1 board and I would like to use the SPBTLE-RF BLE module included. I have read the board datasheet and it indicates that the module uses the SPI1 pins as an interface, but in the module datasheet there isn't a s...
Are there any samples I can order? I don't see it listed on any of the distributor sites. If anyone knows where I can get one that would be great! Also, if an ST rep can state when they will be available to order that would also be great! Thanks
I am working on a project with the STPM3x chip. We have a custom PCBA that does not appear to be working. I am able to communicate with the chip via SPI. I can set the gain registers and read them back. However, the voltage and current measurements a...
I am working with the STPM34/STPM33 chip and using the STPM34 evaluation board. I have noticed in my own hardware and the eval boards that when you attach power to measure voltage it shorts something and blows up. Is this a known issue? Is there a k...
