Resolved! Append uint32 to string for BLE local name

I think this is more of a c programming question rather than a MCU question, but I figured I would ask anyway. I am trying to append the chip ID from an STM32WB onto the BLE local name for my application and am having trouble figuring out how to do ...

Resolved! What are the physical differences between NUCLEO-WL55JC1 and NUCLEO-WL55JC2 Dev boards. Is it possible to convert the NUCLEO-WL55JC2 to a NUCLEO-WL55JC1? The NUCLEO-WL55JC1 seems to be unavailable on the market at this point.

I have own pcb design and calculated rf matching network. Everthing seems good on spectrum alnyzer and i get 20dBm TX out from antenna pin. But i have a problem when send data with sf12. Our gateways not recevie signals. If i chagnge the SF12 to SF11 OK

Can B-L072Z-LRWAN1 Build A Lora Network?

The B-L072Z-LRWAN1 has two examples: ClassA and PingPong. ClassA requires a Multitech Gateway which is expensive, PingPong only for two nodes.If I have 3 to 10 long range nodes, plan to do star network, One node is master and others are slave, can...

STM32WL End Client: GetBatteryLevel() measures Vref+, which isn't likely the actual battery level

Using the STM32WL firmware V1.1, the end-client framework implements GetBatteryLevel() by reading VREFINT and determining what Vref+ is tied to. Assuming that Vdda is tied to Vdd, this measures the Vdd rail. Given motes likely use Lithium cells with ...

Hi there,I want to run some commands and get results on our custom designed STM32wl55 PCB. I started the project using cubemx but there is a subghz linker error.Could you please help me how to solve it?ThanksError: L6218E: Undefined symbol HAL_SUBGHZ...

Is there a 2.0.0 or 2.1.0 version of the Japanese version of I-CUBE-LRWAN? at https://www.stmcu.jp/design/sw_dev/firmware/55524/ I would like to develop for Japan using Murata's LoRa module (type 1SJ).

Setting MAC address on SPBTLE-RF using hci_le_set_random_address does nothing

I'm trying to set the application specific 'random' MAC address on the SPBTLE-RF using hci_le_set_random_address() but I always end up with an address of all FF's. If however I use aci_hal_write_config_data() it works as expected (I get an address s...
