S2LP Question about Versions
Hello, can you help me recognize the S2LP version. I read the register DEVICE_INFO1 and I get 0x91 on the RC-S2LP-433 and in the Steval-fki433v2 is 0xC1. I have some problems with RC-S2LP and I think there is a different version of ic. Thx.
Anyone has ideas for a programmable End Of Line resistors? (CANBUS)
Good Morning everyone, lets brainstorm.Against my will, i might be designing star topology CANBUS networks.So i need to figure out how to set in firmware the EOL resistor value. My ideas:Rele activated EOLs, expensive and bulky.Programmable resistor ...
how go in production using murata module with SIGFOX credential
Starting from ST EVMboard "B-L072Z-LRWAN1" I made my PCB with the murata module "CMWX1ZZABZ-091" (LoRa/Sigfox). To put my board to work, I have done the "id request procedure" with success, the same as I did for EVMboard.Now I am plannig to go in pre...
Hi everyone! I am trying to interface my TETRA device with the microcontroller using the USB interface. The microcontroller will act as a usb host while the TETRA will act as a USB device. I am using STM32F469I-DISCO development board.
How can I do such kind of interfacing. Also note , this TETRA device needs a specific USB driver to install and run while connecting with the PC windows. Does the development board can support only those usb devices which don't need a driver run?
We want to use the S2-LPQTR for proprietary protocols. Therefore we need external control of the TX- and RX-mode of the transceiver. We intend to do this over GPIO 0 and 1, as short mentioned in the datasheet, page 65, table 61.
Do you have a typical schematic or an application note that deals with such a setup, to have direct hardware control of the TX- and RX-mode, and also to access the TX and RX data in a very direct way?In our application the TX/RX time and RX/TX time i...
How many services and characteristics can handle BlueNRG 2?
Hello. I have STEVAL-IDB008V2 and I have 1 service with 5 characteristics for BLE. I use SensorDemo program coming with STSW-BLUENRG1-DK for tests. Problem is that I can not add more services and characteristics because Out of Memory error is receive...
What is the difference between device versions C1 and 91 of S2LP (DEVICE_INFO0) ? Is it any silicon level change or firmware level change?
Is there any silicon level change in S2LP devices with device versions C1 and 91 since we observed there is difference in current consumption in standby mode. 91 is draws 29µA and C1 is drawing < 1µAWhat is the difference between device versions C1 a...
How to implement DLMS/COSEM Protocol on STEVAL-IPP002V1 board.
Hi, I am interested to work on Energy Meter Project by using STEVAL-IPP002V1 Board. but i don't understand how to implement DLMS/COSEM Stack over there.So Please suggest me the implementation steps for this as soon as possible.thank you
ST-Link V3 works well with BlueNRG2 when used from IDE like Keil uVision, but fails in BlueNRG1 ST-Link Utility
Hello,I've started to suspect that something is not quite right with the BlueNRG-1 ST-Link Utility. I have a ST-Link V3 connected to STEVAL-IDB008V1M. I can flash and debug the module from Keil uVision5, but when I try to flash the module from BlueNR...
