Resolved! Do you see an issue with this schematic for programming a STM32WB30CE on SWD?

Hi,My problem is that I have "no stm32 traget found" message when I try to connect to a board by SWD through a ST-Link/v2 (no board identified). On oscilloscope, when we look on SWDIO pin, a little event happens when initializing connection on stm32c...

I-CUBE-LRWAN v2.1.0 + Nucleo-L073RZ + I-Nucleo-LRWAN1 on TTN problem with the end node device

I used STM32WB55RGV6 to make a board (BLE server), the USB dongle is used as (BLE client), and then the USB dongle is output to the computer through the serial port.

I used STM32WB55RGV6 to make a board (BLE server), the USB dongle is used as (BLE client), and then the USB dongle is output to the computer through the serial port. I need to further organize and categorize this data, and then display it as a real-t...

STM32WLE5(RAK3172) - Why do we need to initialize and de-initialize the ADC function again and again for every read, whether this method is effective?

I'm currently working on stm32WLE5(RAK3172) for that module, and I'm using SDK 1.0.0V 1) In that LoRaWAN stack for battery reading implementation, we are noticing that the ADC initialization & de-initialization happening every time.My question is, w...

Resolved! STM32WB55 - ACI_HAL_TONE_START command rf channel resolution

Hi everyone,I use STM32WB55 with the BLE stack 13.0 (full version) and want to test the RF. In the an5270 document, I noticed the ACI_HAL_TONE_START command and it is allowed to change the rf channel from 2.402 to 2.480 GHz with 2 MHz resolution. How...

Resolved! aci_gap_create_connection() returns 0x3a

I have a STM32WB that serves as the master and four other as the slaves.As the slaves may sometimes go offline, the master will periodically tries to connect with them (say, every 10 seconds). Between two connection attempts, the master allows the co...

stm32wb5x_BLE_Stack_full_fw.bin (used resources)

Dear all,I am looking for a reference document listing the resources (timers, RAM, GPIOs, bus clocks etc) that are used by the Bluetooth stack provided byST (stm32wb5x_BLE_Stack_full_fw.bin).Any idea where I can find a complete documentation?Thanks a...

STM32WB55 fails to enter standby sometimes when BLE stack has run

Hello,On a STM32WB55REV, I'm having problems with going to standby.These problems are intermittent (1 in 30 cycles maybe, sometimes 3 in a row, sometimes none for a hundred of cycles...).I only started seeing them after I enabled BLE in my applicatio...
