Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hello Sir / Medam,Greeting of the day.My question regarding wireless charging IC as per bellow:We want to evaluate wireless charging system for which can deliver output voltage at least 15V.So ST have any solution for it?Waiting for your quick respon...
After once BLE Initialize and authentication set by fixed pairing key as "123456" then can we change again pairing key to "123678".Means BLE will disconnected and I will configure its authentication fixed pairing key with other value during run time ...
The ST202EB (ST202EC, ST232EB, ST202EB, ...) RS232 receiver's datasheets shows the following application circuit.Table 7 lists recommended capacitors values for C2-C5 (for the device ST202E is states 0.1 nF, for device ST232 it states 1uF).I think t...
Hi everyone,(I am using TrueStudio/St-LinkV2)I am using the S2LP on a custom board. Everything worked fine (basic transmission, STack packet) until I wanted to use the auto-acknowledgment feature.Following the procedure (DS, 8.1), I have enabled AUTO...
Hello,I am using STEVAL-IDB007V1M and tried to upload the BLE_SensorDemo located on ..\ST\BlueNRG-1_2 DK 3.1.0\Project\BLE_Examples\BLE_SensorDemo\MDK-ARM\STEVAL-IDB007V1M . Compiled it using Keil and my android phone is not detecting it. From this ...
We're using two Blue-NRG2 devices and we would like to implement firmware OTA upgrade without using computer. The goal is to read the binary image file through UART by master device, and then send it to slave device via OTA. Upgrading with BlueNRG GU...
What software/hardware tools do i need to start developing a custom application on these devices?Can I use the embedded MCU to control a few externals peripheral devices so the bluenrg act as main application processor?
Hi I'm trying to get a codec up and running in full duplex using I2S with an STM32F407ZGT6 as MCU. I configure the project using STM32CubeIDE and thus also STM32CubeMx. I have got a skeleton generated but the function HAL_I2S_MSP_INIT that is generat...
Hello when i try to import some TrueStudio example from BlueNRG-1_2 DK 3.1.0 into Cube IDE this one ask me to select the correct MCU and the BlueNRG V2 is not proposed ? Any idea ?
according to the BlueNRG-MS Bluetooth LE stack aci :aci_gap_set_discoverable(......,SlaveConnIntervMin,SlaveConnIntervMax) the last two parameter value range :0x0006~0x0c80,but the STM32CubeExpansion_BLE1_V4.40why the last two parameter are 0???l
