Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
OK, I am Sales guy for ST. No will not support you unless you are in Colorado or Utah.I have seen a lot of issues of connecting ST Micro BlueNRG boards to the development software. Took me a while and no help from ST. But below is what worked for me ...
We are looking at the dual 4x4 crosspoint switch LVDS RHFLVDS2281 and we have a little urgent question regarding the power consumption of the circuit.In the data sheet following is stated:But we can´t find any figures when the circuit is switching, i...
Hi, All.....I am trying to communicate with Android GATT application with Bluenrg-2 GATT."CHAR_PROP_NOTIFY" cannot receive data from Android App.Example ) BLE_Chat, BLE_Chat_Master_Slave by BlueNRG-1_2 DK 3.2.1 ret = aci_gatt_add_char(chatServHand...
Hi,I would like to evaluate the BLUENRG-M2SP module, but I have a question: Does the PCB antenna on this module have a disadvantage over your chip antenna module which is the SPBTLE-RF module? Actually since this is a new design I tend to use already...
Good afternoon,I'm developing a low power radio stack based on SPIRIT1. I encountered a strange behavior in the radio, using the SPIRIT1_Library from ST. I positioned two board within 5cm between each other and using the function "SpiritQiGetRssi" I ...
I am trying to build new firmware for the BlueNRG-2 but am not sure how to configure it as a target. I have looked all over in the documentation and it just mentions that the BlueNRG-2 uses a cortex-M0 processor. I'm assuming it is in the STM32F0 fam...
1. When using the SD interface of stid135 demodulation chip, we found that MCLK output driver is insufficient. We connect the data line of the SD and MCLK directly to the IO of the FPGA, and the FPGA grabs it online, so we can't get it? Can you solve...
I am using BLUENRG-M2 module as a Network Processor (Controller) and an STM32L4 MCU as a host. I want to make the device connectable via Bluetooth during a limited time (e.g 30 seconds) then put the Controller to SLEEP mode (e.g 30 seconds) to save e...
