Hello. I programming STM32WB55 nucleo device and trying to setup printf for debugging. I have no luck so far setting it up. I have tried replacing _write in syscals.c with __attribute__((weak)) int _write(int file, char *ptr, int len){ int DataIdx; f...
How to modify the broadcast frequency of Beacon after it starts broadcasting, I follow the order:aci_gap_set_discoverable() -> Aci_gap_update_adv_data (), but does not work, else(base on BLE_HeartRate):aci_gap_set_non_discoverable () ->aci_gap_set_d...
Hi, Within the framework of a project I have to develop bluetooth beacons in order to determine the positioning of an object in interior. For that we wish to use an STM32WB in order to be used as beacons and that this one emits permanently and transm...
Hi, I'm using STM32WB55x series mcu, I wanna know how I should configure/change the relevant priority for the TIM2?In the old days we use this:void NVIC_Configuration(void) { NVIC_InitTypeDef NVIC_InitStructure; NVIC_PriorityGroupConfig(NVI...
Using an STM32WB55, timer16 for switch debounce. It is set for 100ms. I was looking in the HAL library for the timer and I see start / stop functions, etc. but how do I reset my timer after I come into the ISR? I am sure the counter will roll over...
I am trying to exchange data (str data) between two STM32 throughout Lora connectivity. Both STM32 has a lora module and the connection between them is working fine. Based on two functions:T_eError_eErrorType eDataPlane_eReceiveData_Cmd (uint32_t in_...
Hi,I am a bit confused on the lora STM32WL sequence protocol system, I want my device to sleep and wakeup according to the periodic values I want. I have made my own sleep function (stop 2 mode & radio sleep) with wake up triggered using RTC (in seco...
Hi,I'm hoping that someone can help me implement a Channel Activity Detection (CAD) check on a TX channel before transmitting a message, as to implement a kind of CSMA version of LoRa. Basically I would like to know where CAD is carried out in the Lo...
