I am trying to get BLE_LDD_DataRate demo to work, it just sits there with nothing different from pressing SW1 on 1 board and SW2 on second. Don't have a 3rd board at the moment.The description seems to indicate LED's will toggle, but nothing.I know ...

STM32WB55 bluevoice demo. Peripheral blinks blue, but turns red on SW1. Central blinks green -- on reset of central peripheral returns to blinking green. No code changes, but yesterday green blink was rapid today slow. I can't ask good questions yet ...

I want to create a synchronous link between a few systems. The “master” defines the timing by sending a packet and then waiting for an ack that will contain data. I want the “slave” to be able to calculate the time from receiving the packet until t...

Works with newer firmware download. Now, is there a manual that describes details of BLE LLD? (UM2804 does not have enough information)

Is it possible to gain access to the lowest layers of the radio core such that you can write code that does not use Bluetooth and hence would not require certification as a bluetooth product?

This is not looking good... Here in 2023 I have the same question...

That manual looks like just the thing. I have be struggling a bit with the throughput demo trying to figure things out. HCI_DISCONNECTION_COMPLETE_EVT_CODE does not say what connection from the code because there is only one. The manual answers th...

STM32WB55 BLE LLD DataRate

STM32WB5MMG module. Can this be used in products with varying application (CPU1) code without cert of BLE or RF? Any real-world answers such as it cost us $ dollars and X months would be welcome.

I cannot find a reference manual for STM32WB which includes what the values of the error codes are. 0x48 is out of memory, presently wondering what 0x42 is. Someone could tell me and that would be appreciated, but certainly there is a manual or .h file?

How to make STM32WB bluevoice demo work.

STM32G0/L4/etc. ADC "CALFACT" is obviously some calibration factor, but how do you translate the 7 bits into a numerical value that multiplies the result? Reference manual does not seem to want to say.

Re: While using STM32WB in our product, do we need SIG / BLE certification? even though we are not using BLE logo on the product? Is there any way to avoid certification cost? Thanks !
