Where I can find the wmbus_link.c file?
Hi, I am looking for the wmbus_link.c file, that contents in the WMBUS Library 2013. Could you please tell me where I can find this file?I have read from the document AN4772 with title ‘Wireless M-Bus link layer’, especially in the section 5.3.1- Fi...
Hey I want to create a sensor beacon with a STM32F411RE board and a bluetooth shield IDB05A1. Unfortunately I figured out that the blueNRG-MS package only supports eddystone beacons of the type UID and URL. I think what I need ist the TLM format.
Does anyone have experience with distributing sensor data by a beacon?

BlueNRG-MS missing packets while receiving big amount of data (many packets)
Hi,I am using BlueNRG-MS with STM32L475 MCU.While doing OTA firmware upgrade (over bluetooth) with smart phones, some newer phones seem to send the packets (of 32 bytes, data payload 20 bytes) in higher rate, and as a result once in a while some pack...

Problem of cooperation between SPBTLE-1S module and STSW-BLUENRG1-DK controllers ver. 3.1.0
Hi all,I integrated the SPBTLE-1S bluetooth module in a new own PCB design. I connected the bluetooth module with a STM32L152RC6 MCU thorugh SPI interface. Initially, I used STSW-BLUENRG1-DK ver. 1.0.0 and I programmed SPBTLE-1S bluetooth module usin...
Why the SPIRIT1 (SPSGRF 868 module) enters in MC_STATUS ERROR when I send to it via SPI the command to enter in LOCK status during the "WMBus_PhyInit(MODE, TYPE)" undebuggable initialization function?
Hello,I'm working with a custom board mounting the SPSGRF-868 RF 868MHz module, which embeds the SPIRIT1 transceiver.I communicate with it via SPI, using a microcontroller STM32L151.My board is based on the STEVAL-IDS001V4M evaluation board architect...
