SPIRAW Function of S2LP-SFX-DK

Please let me know the SpiRaw function data format in S2LP-SFX-DK. in_buffer [0] - 0x00 is SPI Write, 0x01 is SPI READ, 0x80 is Command in_buffer[1] - SPI Reigster Address or Command in_buffer[2]~ - Write Data

I have a X-Nucleo-PLM01A1 expansion board, I wanted to use it with a microcontroller from a different manufacturer. Is it possible to do this?

How to make s2lp go to TX MODE

HiI tried to develop my own code for s2lp on NUCLEO-L476RG my setup include:NUCLEO-L476RG+s2lp FKI433v2 on top(RX working fine)NUCLEO-L476RG+s2lp FKI433v2 on top(TX cant go to TX mode)NUCLEO-L053R8+s2lp FKI433v2 on top(as a test for both RX and TX)I...

how to get the MCU version number ? MCU_API_get_version seems to give me different result

sfx_u8* version_m; sfx_u8 size_m; retr_err = MCU_API_get_version(&version_m,&size_m); This works for retr_err = ADDON_SIGFOX_VERIFIED_API_get_version(&version_a,&size_a);   retr_err = RF_API_get_version(&version_r,&size_r);but not for MCU_API_get_ve...

STUSB4500 datasheet VCONN pin confusion

I am designing a device using the STUSB4500 in QFN-24 package. In the datasheet, pin 3 is both specified as NC and VCONN.The pinout says it is NC, but in any example schematics, this pin is shown as VCONN.In different resources, this pin is either be...

S2lP error code "LOW BATTERY Indicator"

I have reference H/W design by X-NUCLEO-S2915A1.It has still have "IRQ_LOW_BATT_LVL" and not send TX data.-Pin1, Pin7, Pin10, Pin15 is 3.3V Level.Could please let ms know if you have any recommend my check point...

How to handle ES_WIFI_STATUS_UNEXPECTED_CLOSED_SOCKET error?

I am using the STM32 Iot Node discovery kit, and I frequently get ES_WIFI_STATUS_UNEXPECTED_CLOSED_SOCKET errors. The wifi reports it is still connected, but obviously there is an issue..How do I properly handle this error and establish a good connec...

BlueNRG-1 ADC input with higher voltage than VBAT sinks a lot of current

According to the datasheet, it is possible with ADC to sample voltage up to 3.6V, even with lower VBAT, if proper attenuator.I'm powering the MCU with 2.5V and feeding battery (up to 3.6V) to ADC1 pin. No matter what setting I use, the ADC is still s...

how to use STM32L1 application code of the BlueNRG1-2 DK package with ATollic TrueStudio ?

Hello , I want to compile the BLE_ChatMasterSlave exemple from STM32L library of the BlueNRG1-2 DK package to test the network coprocessor architecture . The fact is that the code is only compiled with IAR. Is there a way to compile the project wi...
