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?
Hello. I want to use OOK modulation based on GPIO pin. Datasheet says it is capable of doing it, but it is nearly impossible to understand how to set this up.Could Some one provide explanation and register values and settings in order for GPIOX to co...
