RF channel frequency settings for S2LP

I am in the process of migrating from spirit1 to S2LP, I am stuck in the calibration of the frequency, before in spirit 1 it is mentioned in the datasheet of spirit1 via equation 3 fc=fbase+foffset+(fxo/2^15  ×CHSPACE)×CHNUMOn the other hand in the S...

No more message on Sigfox backend when sending with S2-LP_SigFox_DK-GUI

Hi,Three weeks earlier, I connected for the first time my STEVAL-FKI868V2 to the Sigfox backend and used the S2-LP_SigFox_DK-GUI (v.1.7.0) tool to send test messages to this Sigfox backend. Everything worked perfectly.Now since 6 days I try again to ...

Teseo liv3F uses 3 satellites but does not get a position

Good morning,I have been struggling with a custom board that contains the Teseo liv3F. When debugging the module with Teseo suite pro, i can see good signal levels from 3 GPS satellites but the Fix Mode is set to NO FIX and the Lat = Long = 0.How can...

Hi everyone, Here, Present am Working on TESEO-LIV3F gps interface am Trying to read GPRMC and GPGLL through USART interface,

1.In my schematics, my RF section is designed without Capacitors placed(open) , is capacitor need to be added, what capacitor value would you prefer .!2.Is we need to initialize and config for setting parameters in TESEO-LIV3F for GPRMC and GPGLL.Ple...

A call to the GATT Update function aci_gatt_update_char_value gives me the return value 0x20 which is not defined in bluenrg_def.h - so what does it mean? The update fails.

STM32WB5MM Footprint

I'm looking to port a prototype from an STM32WB55 Nucleo board/custom daughter board combo to a single custom board using an STM32WB5MM module. I've done some digging but can't find a recommended footprint for this module. Does anybody know if one ...

BLUENRG stuck when writing BLUE_CTRL registers

I'm working on a custom board with a BLUENRG-2. I'm able to flash and erase with the UART and the SWD pins, but none of the programs work. When I debug it step by step, I find out that all programs hang on this line, when it writes on the BLUE_CTRL r...

What is the difference between memory types connected over FSMC or FMC ?

Hello everyone,I'm using stm32f407 that provide FSMC to be able to interface with synchronous and asynchronous memories and I want to extend the memory so, What is the difference between memory types •NOR Flash/PSRAM/SRAM , the NAND Flash/PC Card an...
