Hi, I am using cubemx to configure a stm32f411ve board as slave in receive only, polling mode and sofware NSS, in the code generated I have only added a few lines of code, only which I consider neccesary**the master sends 12 bytesoutside main functio...
Hi All,I am using "blueNRG-2" MCU, I want to configure it to enter the deep sleep mode.The issue is when the BLE stack is initialized sometimes I can enter the deep sleep and sometimes I can not.I noticed that whenever I can not enter the deep sleep...

1.Pin21-OE Input terminal of output enable (active low), Q1-Is this PWM controlled?Q2-Can use IC without connecting OE pin2.Pin23-R-EXT Input terminal for an external resistor for constant current programming.Q1-Can use IC without connecting R-EXT ...
I am trying to get FOTA updates working with the IoT node kit and Azure.I currently have v4.0.1 installed on the board. I uploaded v4.0.2 to an azure storage account where I created a blob and uploaded the file, then generated a blob sas url.In my Az...
Hi, I try to transmit data by S2LP(RC-S2LP-433) and have a problem. When I try to debug the unit (true studio) everything work great, when the TX end then get an ISR to reset flag and in main loop start new transmitt. When I try to start the unit wit...
Hello,I ask connoisseurs of i2s. How to generate NACK in the slave mode if NOSTRECH = 1 and the slave device sends data to the master?If the slave receives data, then there are no such problems. You can wait for the RXDR to overflow and the slave wil...
See: https://gbhackers.com/sweyntooth/ and https://www.wired.com/story/bluetooth-flaws-ble-internet-of-things-pacemakers/ Per the articles, it looks like STMicro's instantiation of BLE has this issue.
Hi all,When I bring up the S2LP from poweroff, then it correctly reports state=0x00 (READY). After configuration it also reports STATE=0x00. Then I exec S2LPCmdStrobeRx() and it reports 0x3C (RX=0x30 | Lock=0x0C) but then after a second it reports ST...
when running mode, every time it works, but when sleeping, the manufacturer data was missing, and, beacon mode every time works. what's the different of the running mode and sleeping mode of the broadcast?
