Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
There is a bug in S2LP_Library which is part of the STSW-S2LP-DK package. In the following function you need to shift xCcaLength to the upper nibble, but there is no shift in currently available version. The bug won't allow you to set CCA length.Plea...
We know that ST4SIM supports embedded Secure Element(eSE) applet to store and protect sensitive data and provides security services. We think the access to eSE via SPI by STM32 MCU is possible. How can we use this feature?
Hi,I am developing on top of the BlueNRG LP Serial Port example. I have added a few services & characteristics according to requirement. However, while connecting the BlueNRG to a host application (NRF connect), connection & service discovery takes a...
Hello, I am developing a platform with BLE Beacon connectivity and I am looking to extend the range of our device. Until now, I have been using BLUENRG-M2SA module, which is BLE v5.2 ceritifed. I know that BLE v5.1 >= versions include "long range" mo...
VNI8200 has been impossible to source even small quantities (100s) . My customer is exasperated and looking for alternatives. Are there changes in availability expected, other similar ST parts in the pipeline, or should I design it out?
I am a bit confused about the number of connections the BlueNRG-LP can handle.The device is advertised with 128 concurrent links.I visited a ST talk where the discussed number was about 50 Connections.I used the BlueNRG-LP 1.0.0 Radio Wizard that lim...
At the moment with the X-NUCLEO-PLM01A1 + Nucleo-F401RE boards is supplied a firmware stack with only PHY and DATA link.What full stack do you suggest to use with ST7580?An old job of Nunzio Dipaola (Application Note AN4411) build a 802.15.4 stack ov...
Recommendet is 66µm CU with 305µm distance to ground layer. I would like to have 35µm CU with 180µC distance to ground layer.
I am using a BlueNRG-LP MC355 SoC. When connected to my debugger, I can call NVIC_SystemReset() just fine. However, if I disconnect the debugger, the device hard faults on reset.uint8_t ret = BLE_STATUS_SUCCESS; uint16_t service_handle, dev_name_...
