Hello,We are using the SPIRIT1 with a 50MHz crystal (as part of an SPSGRFC-433 module); I've configured it to MSK, with a base frequency of 433.175MHz, a data rate of 250kBaud, which leads to a configured frequency deviation of ±62.5kHz. I've set a b...
I am building a board that will use both the STM32L4R5VIT 100pin package and Bluenrg-2 232. I would like to JTAG chain the two processors so that I can use my Segger Jlink to debug both processors from the same debug connector. The pins to use for JT...
Hello,In case I have the following case:Vcc=3.3V, VL=OE=0V, I/OVL1 = 0VWhy is I/OVCC1 at 3.3V with OE=0V?Best regardsMich
Initially when bond is disabled, BLE works fine. But when bonding is enabled through AT Commands and board is reset, I get error like "Error in aci_gap_set_discoverable(): 0x42". I am storing the Bond status in nvm. Is nvm making the issue? I suspect...
Hi all,Where can I find code example for STM32F429zi ram drive codeI see FatFS and other examples, but no ram-drive FatFS exampleI need to open a device over USB to be recognized by the PC HOSTThanksEli
Hi! Is anybody have a schematic with a BALF-SPI2-02D3 + SAW FILTER? Is this wiring will be good?
Hello I'm try to connect 1 master and 2 slave, but failed, I use stm32f427VI, and use Truestudio for programing, thanks for your help./* SPI4 init function */ //SLAVE1 static void MX_SPI4_Init(void) { /* SPI4 parameter configuration*/ hspi4.Ins...
Hi,I am using a SPBTLE-RF chip and will switch to the BlueNRG-M0A soon. I am willing to estimated how much I will benefit in term of signal strength using this new chip.SPBTLE-RF chip is advertised (on website) to have a maximum +4dBm TX power output...
Hi, I am working on a USB PD project. STUSB4500 is used to request the 20V/12V 3A from the source. I flashed the NVM inside of the IC. The writing on the NVM seems to be successful as I can read it back and verifiy it. After reconnecting it, I can re...
I'm using the BlueNRG-2 with FreeRTOS in Atollic TrueSTUDIO.I succeeded in scanning for beacons using:ret = aci_gap_start_observation_proc(160, 160, 0x00, 0x00, 0x00, 0x00);But after some time I would like to stop scanning and e.g. enter sleep mode a...
