Resolved! SPWF01: ''Failed to resolve name'' Error
Posted on October 05, 2017 at 12:38Hi,sometime I get the error 'Failed to resolve name'. I always call the same address - so the address is valid. If I get this error I have to reset the module.What failures cause this error?BR,Flow
Why are all MAC callback functions in I-CUBE-LRWAN moved to lora.c ("inside the stack") and statically defined? (in Stackforce this is not the case)
While working on a standard OTAA Rejoin procedure for our application I've noticed the LoRaMAC callback primitives are all fixed in the LORA_Init() function. When I want to catch the event the MAC layer signals the reception (or not) of a server ACK ...
How to read the temperature using the mlx90614 sensor with the stm32f1 microcontroller
I'm trying to read the temperature using the MLX90614 sensor, however I can not get into the project. I'm using the I2C communication protocol and the code provided below, and I get the value 0 when I read it in the variable buffer.After many attempt...
What's the maximum value of the sum max_attr_records ?
HI dears,I am working with BLUENRG-MS stack using spbtle-rf.After some tested I noticed that there is a limit to the number of services/charectiristics I can add the BLE.How can I calculate that limit or when I can find this information ?Regards
SPIRIT1 CSMA
According to the description of CCA_PERIOD[ ] on page 41 of the ref manual (DocID 022758 Rev 10) , Tcca is the time between two successive CS samplings but the CSMA flow chart on page 40 indicates that CS sampling is done continuously for Tcca durati...
Converter PLC to CAN Electrical Vehicle
Nowadays I´m working development a converter in PLC (CCS) to CAN (CHAdeMO). But I don´t have sure about the best Evaluation board for this task, because I don´t know frequency in EV and EV supply. I thought EVALKITST8500-1.https://www.st.com/en/eval...
How to switch seamlessly the BEACON mode and the THROUGHOUT mode by UART AT command on BLUENRG-1 hardware platform?
I want to place the BEACON mode and THROUGHOUT mode into one project on BLUENRG-1 hardware platform, and send AT command to switch seamlessly between two modes. Now I know how to work in one mode, but could not switch mode. How to do this?
S2-LPQTR & ISO 18000-6c/EPC Gen2
Just was wondering, would a S2-LPQTR module be able to be used as a transceiver to create a microcontroller based EPC Gen2 RFID (860-960MHz) card?"An Interrogator sends information to one or more Tags by modulating an RF carrier using double-sideband...
