I am using the B-L475E-IOT01A kit. I want to use spsgrf sub GHz module. There are only libraries available for that. Is there any reference manual available that can be referred to?
I want to understand more about registers and RF activities.

Resolved! How to start BLE advertising again after a disconnection from the central Android device
I am a student who is currently doing his bachelor thesis. My job is to control two microcontrollers (Nucleo-STM32F411RE) via Bluetooth (X-Nucleo-BNRG2A1) in order to transfer parameter values for a system. The idea was to connect the microcontroll...
I am trying to send data over bluetooth to stm32f411 board. I am using HC-05 v2 bluetooth module which communicates over UART interface. Below is android studio code and stm code
When I'm sending data from computer it works perfectly- data is sent and STM's response is received over UART in RealTerm. However switching to bluetooth module and sending and receiving data from android app doesn't work as expected. For now I want ...

Resolved! S2-LP: Correct procedure to change frequency?
Hi there!What is the correct procedure to change the S2-LP's frequency after it has been initialized with a call to S2LP_RADIO_Init()?After I call S2LP_RADIO_SetFrequencyBase() the S2-LP appears to lock up. MC_STATE1 = 0x52 and MC_STATE0 = 0x29 which...
L6362A open wire protection
In the datasheet for the L6362A, section 11.8 mentions putting an external diode on OUTH or OUTL to protect against an open wire on VCC or Gnd. Looking at the block diagram of the chip, I don't see what the purpose of those diodes is. What am I mis...
