Dear Sir/Madam, We are the hardware engineer from Siemens Suzhou, our project used BLE chip BLUENRG-M2SA. Now we are preparing to pass the SRRC certification with our product, so where can I found the CE/FCC/SRRC certification docu...
I trying to read iBeacon adv data for uuid, major and minor. But I notice I only able to get the address. I tried to print out the AD data, but it always tell me its empty when iBeacon is detected. Please help./***************************************...
Hello everyone,I've designed a PCB With a STM32H7 which is supposed to control a BlueNRG-MS. The design is the similar to the Figure 6 of the component datasheet: https://www.st.com/resource/en/datasheet/bluenrg-ms.pdfI didn't put XTAL1 since it's op...
We are using the STUSB4500 PD chip in one of our applications. The requirement is to set the Power delivery to 12 V and 5A for the sink. I have been referring the driver code provided by ST to program our microcontroller. To set PDO to 12 V and 5 A, ...
Hi,There are three type of source PDOs:Fixed SupplyVariable Supply (non-Battery)BatteryDocuments gave examples for the decision algorithm for Fixed Supply type source PDOs. But for Variable Supply (non-Battery) and Battery type of source PDOs, the vo...
Hi,I have bought 2 BlueNRG-Tile and would like to try out the application as per link below.https://my.st.com/content/ccc/resource/technical/document/application_note/group1/43/8d/b8/4e/44/91/4b/64/DM00712091/files/DM00712091.pdf/jcr:content/translat...
I have a blueNRG-2 chip on hand, and I am looking to program the chip to have the ability to connect to android devices (for a project). Am I correct in my thinking that I need a BlueNRG-M2SA module in order to achieve my end result?
I am using BLE Scanner app to write data to a characteristic in BLE device. I sent 35 bytes of data, but the device receives data 20 bytes per write operation and then receives 15 bytes more. How to receive all the 35 bytes with single write operatio...
Hello to all,I succesfully upload the DTM_SPI firmware on my X-NUCLEO-BNRG2A1 board, , using the SWD, but the BLE chip is no more responding. I'm using the X-NUCLEO-BNRG2A1 with a STM32L476RG-Nucleo, and I tried the "SampleAppThT" application to set ...
