Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hi everyone,I am developping an application on the BlueNRG-M2SA module (BLE 4.2) supporting Multiple connections.In my case, the BLE device is configured as PERIPHERAL and is able to serve two connections from two different Android devices simultaneo...
I have B-L462E-CELL1 development board with ST4SIM200M IC. this board came pre-provisioned with the Truphone profile but I didn't find any way to add a new profile. According to the datasheet eSIm chip supports up to 7 profiles but How can we add and...
Hi, I am using a SIM7600 and a SIM card to get cellular connectivity. Now I would want to use an e-SIM instead of the SIM card holder. However I cant find information regarding if ST Electronics e-SIMs could use any cellular network provider or if it...
We have used the STKNX IC in our Product as transceiver. In the ESD Test, the IC failed to sustain. The layout and components of the peripheral circuit is as per datasheet and reference from EVALSTKNX Board. Please guide urgently.
Hi everyone, In my company, we are currently working on the IOT solution that implements ST4SIM-200M module on our PCB. To shorten things up, we are using SIMCOM modem with the psychical SIM card and it's working ok as we expected. Our next step was ...
Originally a reply to this - split to a separate thread as it is a different STM32, different radio, and a new question.Thank you for your answer. I may consider embenet as option. Another thing that I'm trying right now is Contiki NG. I use STM32L15...
Hello, We are evaluating Bluetooth capability to our system using ST Bluetooth module, in order to eventually use BLUENRG-M0A in our company products.We are using STEVAL-IDB008V1M BlueNRG-M2SA evaluation platform connected to STM32H735 host.Our goal...
I’m testing S2-LP sub-GHz transceivers in stack packet mode. I’m encountering an issue where the sequence number in ACK packets sent by the receiver doesn’t seem to be populated correctly. If I’m not mistaken, when automatic acknowledgment is request...
Posted on March 22, 2018 at 05:25I have an interface product have some chips carry ST logo, but I can not find anything use the Chip ID. They are EZ026 and EZ030. Can anyone help to identify what is these chips? Here is the picture shows the chip.Th...
Hi,I would like the DC/DC converter of STKNX to make 5V.Also, I want the Linear regulator to make 3.3VBecause of global efficiency, I wanted to power the linear regulator with the 5V output of DC/DC converter.I'm surprised that the datasheet specifie...
