Resolved! FSK bandwidth selection documentation error?
In 5.5.3 FSK modemBR = 32 x HSE32_freq / BitRate where HSE32_freq = 32 MHzFdev = Fdev[Hz] / FreqStep where FreqStep = HSE32_freq / 2^25The document then states that to ensure correct modulation the following limit applies: (Fdev + BR/2) < BWIn the...
STEVAL-ASTRA1B - I can build, flash and debug via stm32cubeide. Alas, the STAssetTracking app won't load on my android moto g pure. Alternatives?
Question1) is there a way to input the needed "commisioning" data (that the STAssetTracking app would do via BLE) into the ASTRA and start the OTAA for lorawan?Question2) is there an application note for the above question? or some other doc (already...
How to disable OOB?
STM32WB55 as a central (client)Sending ACI_GAP_SEND_PAIRING_REQ and getting ACI_GAP_PAIRING_COMPLETE_EVENT with failed. reason: AUTH_REQ_CANNOT_BE_MET.As I matched all the other settings to the server(peripheral) device settings.Was curious if the OO...
Why is pairing taking so long?
I am using the stm32wb55 as a Central.When pairing to my server, I encounter long pairing times.About 80 seconds from the moment I send the passkey to the time I get paired complete event..(I have no errors in the pairing complete event)I did not hav...
Resolved! STM32WB programming time during production
Hello,I developed an application to automate the programming of the STM32B55xx, since I have a batch of more than 10000 parts. I used the documents AN5185 and UM2237 as a basis. For this product, I am using FUS version v1.2.0 and the "stm32wb5x_BLE_S...
STM32WB55RGV6 What is the maximum payload per notification (BLE server)? How do I need to modify the program？
I want 120bytes per notification, I want 120bytes per notification, but I can only reach 20bytes with stm32cubemonitor-rf monitoring.The following picture is what I mainly modified in the program：Am I going wrong somewhere?
STM32WB55RGV6 ble The larger the number of bytes per notification, the slower the transmission interval?
15bytes per notificaiton, interval about 7.5ms120bytes per notification, interval about 30msI want to change 30ms to 10ms. How can I do?
Resolved! How can I reset ADC measurement for the next measurement?
Right now, I'm focusing on increasing ADC channel.I assembled the STM32WB55VG microcontroller and 8:1 mux.The mux is contolled by three GPIO pin for [2:0] encoding to select channel.The output of mux is connected to the ADC and I can see the ADC data...
STM32WB55RB can't allocate memory after GPIO Interrupt
The problem can be simplyfied to this code:int startFlag = 0;void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ startFlag = 1;}int main(){ if(startFlag== 1){ //crashes at first iteration (Hard_Fault_Handler) int *test = malloc(sizeof(i...
