[BlueNRG-MS] Can't connect to gatt server with Android device

Hello,I created a BLE peripheral using a BlueNRG-MS chip. I can connect on this peripheral using a BlueNRG-M2 (using BlueNRG GUI) and read the services.However, it does not work when I try to connect with an android device (I use "BLE Scanner" app, B...

Debugging the STEVAL-IDB011V1 via CMSIS DAP

Hey all, We received our evaluation kit in the mail today and I'm trying to get some "Hello World" projects running. I'm using IAR 8.50.4 and have had success flashing the example projects to the board using the Navigator and by dropping Hex files in...

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...
