Good afternoon eveyoneWe want to replace the conventional capacitive touch screen with a resistive touch screen. Capacitive touch screens do not require calibration, but resistive touch screens require a first calibration. I know there is a touch c...
Hello, I am using stm32F429zi as TCP server just like in the example project "echo server" and my application needs to responding every time on the same port, but after disconnect and connect to the sever it changes port. Is there any way to force re...

I am trying to implement a working MESH network without the participation of a smartphone. The idea is to send messages from all test nodes to one specific node through the MESH, which has the same hardware structure as the rest. This node should pro...
I am using a B-L072Z-LRWAN1 and the STM32CubeExpansion_LRWAN_V1.2.1 End node example with an 8 channel lora gateway set to channels 1-8. The gateway is receiving some data from the End Node. Appears the End Node may be transmitting on channels that t...
Posted on January 07, 2018 at 03:35 Hi I have my custom RF board using S2-LP and balunBALF-SPI2-01D3 ( /external-link.jspa?url=http%3A%2F%2Fwww.st.com%2Fcontent%2Fccc%2Fresource%2Ftechnical%2Fdocument%2Fdatasheet%2Fgroup3%2Fe9%2Fff%2Fcd%2F1e%2F4...
Hi I need to export configuration from my S2-LP soldered on my board. I succeed to export S2-LP in eval board using S2-LP DK tools, but, i can't display S2-LP register soldered on my borad (can't connect to my board with S2-LP DK tools). Is there a s...
I'm trying to add a custom GATT service to a HID peripheral. I'm using a BlueNRG-2 and following the BLE_HID_Peripheral example. In the hidService_Type ther are two fileds that look like they might be used for this. They are includedServiceEnabled an...
Hi, I'm using the example "BLE_SensorDemo_Central" from SDK to design a PoC to scan iBeacons devices.I can't figure out why the scan procedure is too slow. I have two iBeacon devices near by the BlueNRG-1. They are sending iBeacon messages in 3Hz, bu...
Hi,We are using the BLUENRG-MSQTR chip in a PCB assembly design that also has a 1.62 GHz transmitter on the board. Our PCB schematic and layout are as least as good as to what is recommended in the application notes. Particular attention was made for...
