Buggy command ACI_GATT_DISC_READ_CHAR_BY_UUID stops to work

Hello Dear,Was debugging this command today, and unfortunately found it to be working only partly.From what I see, is that the command aci_gatt_disc_char_by_uuid_cp0 occasionally works and occasionally doesn't.Currently developing on the stm32wb55, ...

Resolved! STM32WL (SX1262) vs S2-LP (CC1101) data whitening algorithm incompatible?

Hi there! We are developing a new STM32WL based product that must be compatible with the existing STM32L0 + S2-LP products. It appears that the GFSK data whitening algorithm is different(?). I used an SDR dongle to sniff the raw bytes transmitted...

I see that the STM32WB55xx supports a Rf amplifier using Pin PB0 as TX indicator. Is there any provision for a external pre-amplifier RX indicator and sleep mode indicator to drive a external FEM such as the SKY66112? It needs TX,RX and Sleep mode inputs.

CE declaration of conformity for P-NUCLEO-WB55

Hello, I'm looking for the declaration of conformity document for the P-NUCLEO-WB55 pack [MCU STM32WB55RG (Nucleo68) and MCU STM32WB55CG (USB Dongle)]The document I need should reference the RF standards that the product is in compliance with.I check...

Resolved! Processing when BLE is disconnected during data transmission with BLE

I am using STM32WB5MMGH6 as a slave and communicating with the host using BLE.The question I would like to ask here is is there a way for the user to detect when data transmission fails due to BLE disconnection, etc. during data transmission?The tool...

P-NUCLEO-LRWAN2 - Sensor-board trouble with AT commands

Following section 4 in UM2587, I've connected an FTDI UART-RS232 adapter to the I-NUCLEO-LRWAN1 sensor board to read the APPEUI but I don't get any response. I've also tried reading from memory 0x08080000 of the NUCLEO-L073RZ board, but I only get ze...

not entering stop mode - STM32WB55

I understand that C2 manages the power state automatically. I have confirmed this using the Cube power monitor utility, seeing that when there's no RF activity power draw on an the st32wb55 nucleo eval kit falls below 3uA. This was done with a simple...

Is it possible to seperately use RTC with BLE?

Board: STM32WB55Software: RTC and BLEHello,I am trying to get a project set up on the above board. It needs BLE, USB and RTC seperately. I have the USB running with Bluetooth now thanks to a relatively recent post offering a means to fix the incompat...
