Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I have a blueNRG-2 chip on hand, and I am looking to program the chip to have the ability to connect to android devices (for a project). Am I correct in my thinking that I need a BlueNRG-M2SA module in order to achieve my end result?
I am using BLE Scanner app to write data to a characteristic in BLE device. I sent 35 bytes of data, but the device receives data 20 bytes per write operation and then receives 15 bytes more. How to receive all the 35 bytes with single write operatio...
Hello to all,I succesfully upload the DTM_SPI firmware on my X-NUCLEO-BNRG2A1 board, , using the SWD, but the BLE chip is no more responding. I'm using the X-NUCLEO-BNRG2A1 with a STM32L476RG-Nucleo, and I tried the "SampleAppThT" application to set ...
hi,We designed a board using BlueNRG-2 and we uploaded the GPIO demo code available in BlueNRG-2 navigator (to toggle DIO14) to the board using the BlueNRG-ST- Link utility. The board didn't detected with high Frequency(.9MHz-4Mhz) so we changed the ...
Hi all, I am using X-NUCLEO-BNRG2A1 with NUCLEO-L552ZE-Q board. I have created a project with STM32CubeMx using X-CUBE-BLE-2 SensorDemoBLESensor Application, mapping the pins of the expansion board to my nucleo board as :PA5: SPI1_SCK ==>I s...
The problem is that the convert/chip-select pin needs to be asserted for about 700ns for the conversion to complete.The NSS signal of the stm32f4 only is asserted a very short time, so that would not do.Maybe use a timer to generate the convert pulse...
Hi,I am trying to implement CSMA feature on S2-LP. I am working with SDK_Csma_X examples. The SDK_Csma_A example is a transmiter and the SDK_Csma_B is receiver. I have to have the transceiver. When I combine the two examples there is no acnowledgemen...
Researching other BLE products found that many BLE devices include the Device Information service, which includes the device manufacturer, device software and hardware version, product number and so on. I wanted to know how to add Device Information ...
Hi, I'm using Bluenrg2 chipset on a custom board and bluenrg (UART pins) is connected to the PC via USB-2-uart connection. Is this okay? What is the requirement to connect Bluenrg SW GUI with custom board without STM32With the above mentioned connect...
