Resolved! non-const pointers as ACI commands' arguments

I wonder why are all ACI commands, that imply using pointer-to-const parameters actually use non-const ones? Is there any reason? Will it ever be fixed?For example:tBleStatus aci_gatt_add_service(uint8_t Service_UUID_Type, ...

B-L072Z-LRWAN1, STM32CubeExpansion_LRWAN_V1.3.1, End Node application: 50% packet transmission failure to gateway

I am running the above mentioned board about 3 meters away from two gateways, a TTIG and a RAK7258. I made two modifications to the stock End Node application - I modified Commissioning.h with the EUI, etc. for one of the gateways (have tried both)...

Resolved! STM32WB50 Errata

We were planning to replace our STM32WB55 design with an STM32WB50CG, unfortunately we saw the errata document DM00625356.In particular we need to operate with LSI2 for the Bluetooth and cannot add an LSE crystal.When will there be a silicon revision...

Resolved! Bug in CubeMX code generation for SPI/DMA

I think I have discovered a bug in the way CubeMX behaves when both SPI and DMA are enabled. I am using the P-NUCLEO-WB55 board. If you look at the SPI_FullDuplex_ComDMA_Master example application, this runs fine on the P-NUCLEO-WB55 with a jumper be...

LRWAN: duplicate frames

Stack versions: LRWAN_V1.3.0, LRWAN_V1.2.3, LRWAN_V1.2.2Hardware: B-L072Z Murata moduleWe are registering duplicate frames sent by the End Nodes. Doesn't happen frequent: 1% of all frames, may be less.It happens on over all of our LoRa gateways so it...

Is it possible to get 802.15.4 MAC running with low power modes?

In AN5289, clause 12.4.5, I found, that "Low power feature is not supported". I'm wondering what actually doesn't support low power here: application example for MAC 802.15.4, the wireless stack or neither. Also, if it's the case with the wireless st...
