Is there a possibility to use the STM32WBxx with wifi?
Is there a possibility to use the STM32WBxx with wifi? I know it can handle bluetooth or zigbee.Or maybe is there in the near future a firmeware upgarde to use wifi?Thanks!
What is the fastest adc conversion speed using DMA and external trigger based the chip timer peripheral.
According to manual I should getFast channels: 0.234 μs for 12-bit resolution (4.27 Ms/s)Slow channels: 0.297 μs for 12-bit resolution (3.37 Ms/s)but I am getting only get 2Ms/s.I am clocking the chip at 64MHz and using P-NUCLEO-WB55 evaluation board...
Hi i have the B-L475E-IOT01A Discovery kit and want to connect to a LoRaWAN Gateway. Which extension board can i connect to the discovery kit to establish the communication. The Sub-GHz module supports no LoRa modulation scheme.

I-CUBE-LRWAN Software Expansion 1.3.0 Does not work
I have loaded SE 1.3.0 out of the box (only changed app and dev ids) onto a Nucleo board, and after a few uplinks (data) the loraserver does not send a downlink confirmation, as if the fcnt is incorrect. In fact the fCnt is OK. It could be that the M...
Writing a program to the controller
Hi). I made a minimal design for STM32WB55 on board. This board has 3 program pads. There ara GND, SWDIO, SWCLK. Сontroller current is 11mA at the factory program. I try to flash the controller using these contacts, but nothing works. I use ST_LINK (...
