I need to be able to transmit or receive I2C frames of several hundred byes. But the FIFO size is only 16 bytes in TX and RX direction. The sample code from ST only uses less than 16 bytes so it does not check the status of TX or RX FIFO.In my case,...
My evalboard seems to work. (I can flash the demo projects)But when I try to use the GUI, it does not detect the device. "No Firmware detected on motherboard..."It is successful to flash the Firmware STEVAL-IDB011V1/USB_CMSISDAP.hex but afterwards e...
So the details of the configuration are: i am using I2C3 peripheral with the clock speed of 100kHz the pins are set to open drain no pull up no pull down. I am also using external pull up ressistors.I have already checked the internet for a solution ...
It's the first time that I have to set RF modules.I have the following RF modules: S2LP of ST and CC1101 of Texas. I need that they communicate togethar. Do you know if they are compatible?I know that in the module C1101 you can select 2GFSK modulati...
I am unable to build the source code provided on ST's gitHub due to the following error: "Building for iOS Simulator, but linking in object file built for iOS, for architecture arm64"The recommended solution I've found is to explicitly exclude arm64 ...
Hi,I was reading the BlueNRG-2N features on this datasheet, and it stated that it could "handle up to 8 simultaneous connections."Does this mean that one GAP Central device based on the BlueNRG-2N could transmit up to 8 GAP Peripheral devices (also c...
Hi EveryoneI can't achieve the 500kbps using the following setup, which according to the S2LP datasheet is possible:HW Setup used for the test:main boards;STM32L073 Nucleo-64 board MB1136 Rev. CRadio boards:X-Nucleo S2868A1FW loaded into Main boards:...
Hi,I am trying to use subGHz RF modules in my design. I have following questions. It would great if any one could answer these questions. I am trying to build sensor nodes + Gateway. Planning to use mesh over sub GHz.What is the difference between S2...
Hello,I created a BLE peripheral using a BlueNRG-MS chip. I can connect on this peripheral using a BlueNRG-M2 (using BlueNRG GUI) and read the services.However, it does not work when I try to connect with an android device (I use "BLE Scanner" app, B...
