Interface and connectivity ICs

HW: ​BlueNRG-1 development platforms (order code: STEVAL-IDB007V1)GUI: BlueNRG4.4 I followed um2071-bluenrg1-bluenrg2-development-kits-stmicroelectronics to try to upgrade the firmware. the LED2 is flashing.....buf upgraded fail. Is there any wrong or missing about my opreation? thanks!

Hello guysHave ST an Official or Unofficial firmware for BlueNRG-LP that enables control it over AT commands?Regards,Leonardo Trinta

I need a DTM firmware for BlueNRG2 which works wirelessly with the equipment shown in the image. I wonder if ST provides their customers with such a firmware? thanks,

We have connected the BlueNRG-232N to a host processor using the UART.The BlueNRG-232N should function only as a BLE interface, as a way for the host processor to communicate with a smart phone.But I'm stuck on how to do this, do I need to load the BlueNRG-232N with a c-program ?Maybe I misunderstood, but I read that the BleuNRG-232N was pre-programmed ?

Hello. I'm interesting about ST202EBTR. If I use it in 3.3V, what difference is it compered in 5V.

We have a L152RE module connected to a RF transceiver called X-NUCLEO-S2868a2. So, our mission is to measure some frames received from a water gateway by WMBus. We have implemented the firmware SUB1GHZ (written by ST). We receive the first block of the protocol but in the second one, there's one byte that repeats itself always.Here's an example:2e44ae4c994000027807a6b97a0b902005 3939393939393939393939393939393939393939393939393939393939393939393939393939first block (header)                              Second block (Payload)We are using the software downloaded from STM that I mentioned before. Payload should be encrypted but in this example is not, and we don't know what is it. Besides, I measured it with another device and it shows different bytes.Do you know what could it be?

Hi,I'm using BlueNRG- M2SP module & I have downloaded BlurNRG M2SA example code. In the application manual, it is mentioned that some data need to be changed like "HS_SPEED_XTAL", "LS_SOURCE" & "SMPS_INDUCTOR" while porting an existing project from BlueNRG M2SA to M2SP module and I have changed that. But only the UART peripheral program worked properly rather than that of BLE examples. GPIO toggling example is also not working, pins are not changing their states. I want to know whether there should be any extra changes required or not in M2SP module. Thank You...

What eSIM has been used in this P-L496G-CELL02 EVK?The B-L462E-CELL EVK is using ST4SIM-200M in the board. Would like to know the differences between the boards.Thanks.

Hi,I use a BlueNRG-1 with exemple HID KEYBORD. I want to bypass the serial keyboard for sending a small world ex: "test" when i push User button.Somebody can do that and apply change program ?Thank

Hello friend,I programmed a blueNRG-1 MCU using ST Link V2. But I need to use BlueNRG-1 ST -Link Utility's application to erase MCU and need to pull up a pin (for SWD program). Then unplug the ST link V2 and plug it in. Release the pull-up pin and use the application of BlueNRG-X Flasher Utility 4.0.0 to burn the firmware and BD address at 0x10005fff4. This is very inconvenient. Does anyone have a convenient burn-in program for MP to use.Thank you in advance.Ted Wu

WiFi uses significantly higher output power. I assume that the WiFi signal is perceived as noise by the BlueNRG. (Please correct me if I am wrong.) To receive a signal from a second BlueNRG-LP, the received msg signal strength must be higher than the WiFi noise. Am I right? If so, how much higher must this signal be? x dBm?Thanks a lot!

I want to operate the ST7580 in higher ambient temperature (iro 150 C) - not really interested or too concerned about the impaired longevity

I'm using vbus to power supply the MCU, through a voltage regulator. For the MCU I'm using the stm32f427, not the 39, as in the development board, but they seemed compatible with my project features.When I connect the board to my laptop via USB, the overcurrent led turns on, and my operating system (ubuntu) does not detect any new USB device.If I connect boot0 to VCC, the command lsusb in ubuntu takes some seconds to respond.Can you please give me some suggestions?Thank you in advance

Hi,How would one implement PLC together with a combination of NUCLEO-PLM01A1 and STEVAL-XPLM01CPL?how would i need to hook up the circuitry between those two boards, so I can safely communicate over AC lines.Best regardsRené

described in table 8 of BlueNRG-M2 datasheet. But there is no description of what the Mode is.Is it a pin or SW configuration or model type?

Hello, wanting to use the Bluenrg-232 in a design using the typical application. Where would I find the values for the components?Thanks

Hello.I want to get the results through unicleo-gui using the sensortile kit.I soldered sensortile to the cradle.Before soldering the sensortile to the cradle, I connected it to the expansion board and checked that it was connected to the mobile phone application by Bluetooth.When connected to the computer usb line, the red light keeps turning on when the cradle is switched on, and when the switch is turned off, the red light blinks quickly.I want to connect with the computer's unicleo-gui while the computer's USB line and cradle are connected.However, as things stand, the computer and sensortile(soldered with cradle) are not connected via Bluetooth.Is there anything I can do now?Do I need to install firmware or is there another problem?If I need to install firmware, can you explain the detailed method?I've been thinking about this for quite a while.I'd appreciate it if you could let me know.Thank you for reading it.

M41T00SM6F:Can we RTV if fail solderability test?

I'm working on a project where I need to send and receive http requests/response over tcp/ip, I can get only 3 ethernet modules from my local store - ENC28J60/W5500/W5100. After doing some research I found out basically all 3 of them can work for me, but at the same time none of them have proper HAL library I can use to easily implement them in my project.So I need an advise on whichever one of those 3 I should use, which would be simpler to add and work on?If anyone already used them in HAL previously and already has a working library I'd appreciate it, otherwise I'll need to port them from Arduino libraries.
