I have a simple project I am trying to implement using BLUENRG2-M2SA. It will connect with a user over BT and download a timer length. Then it will run the timer and blink lights when the timer counts to zero. The user then acknowledges the lights...
Hello,I'm developing a board with the BlueNRG-M2 module. I'm also using an ST-LINK V3 with uVision to debug/program. I'm also using the VCP made available by the ST-LINK V3 for some good old fashioned printf telemetry. The VCP is connected through...
Trying to build a 433 MHz sniffer based on SDK example "SDK_Sniff_B.c". Im sniffing messages from TPMS sensor and get them on my PC with RTL-SDR. In the message parsed on PC I can read ID of sensor which goes right after sync word. With the help of U...
I want to use hyperflash (S26KS512 or S26KL512) with stm32h723zet6 microcontroller.The memory has "Phase Shifted Clock" pins.What should I do with them? Connect to GND or VCC or Not Connected?Hyperbus interface (stm32) support 1.8v?
My main problem is to reduce the power consumption of the HC-05 Bluetooth module. As it may be known, such a module consumes lower and lower energy when it is in the AT Command Mode (between 1.5 and 3 mA current). Since my project requires sending re...
Hi ST community! I have been using BlueNRG for the next version of product in our company. I have a problem with pairing this module with phone. Once I paired with device, they are supposed to be connected even after phone restarts, but it is not the...
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...
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 ...
I'm using a X-NUCLEO-BNRG2A1 shield on a NUCLEO-L476RG board.I am able to advertise 16-bits and 32-bits services using aci_gap_update_adv_data(), but trying with a 128-bits service always ends up with a "BAD PARAMETER" error. What am I missing? (I'm ...
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...
