Posted on May 12, 2018 at 05:47Hello - wrt the maximum total size of a BLE advertisement or scan response of 31 bytes:The BlueNRG-MS v7.2c Peripheral can generate either at max expected length.But when I run the BlueNRG-MS v7.2c Central, if the tota...
Posted on May 17, 2018 at 16:12Hi !I have to implement a connection method with an authentification between a blueNRG-MS BLE device and a mobile app. The BLE device has no I/O capabilities so following the BLE spec v4.1 soi have to implement just wo...
Posted on April 25, 2018 at 11:18Hello, I want to make a PCB with a microcontroller STM32L476RG and a Bluetooth module SPBTLE-1S. I plan to use the SPI for the communication beetween the microcontroller and the BLE module but I don't know which pin ...
Posted on May 15, 2018 at 15:18On one of my boards that use the SPWF04 module I have started to see Win7: Configuration Failure:4 which from the manual indicates the RTC cannot be initialised.For these errors my approach was to hold the device in re...
Posted on May 15, 2018 at 12:35Hello!I am using BlueNRG-1 device with BLE stack v1.0.Can you please advice me, if there is a method of pairing using IO_CAP_KEYBOARD_ONLY on device, if I want to always send FIXED code for pairing? I want to send the ...
Posted on February 13, 2018 at 14:49Hi,I have a question about the STEVAL-FKI868V1 development kit that is based on the S2-LP sub 1GHz transceiver. We have a system that works at 868MHz and the signal that commes from the system is fed into multiple...
Posted on August 04, 2016 at 09:33Hi, The description in the .h file states that: '' * @param en_high_power Can be only 0 or 1. Set high power bit on or off. It is strongly adviced to use the * right value, depending on the...
Posted on May 12, 2018 at 06:46Hi,I am able to communicate with BlueNRG-2 either by ST-Link Utility or by Atollic GDB. Unfortunatelly, when I start regular work of DTM firmware, these tools lose communication.What is the reason of that?Is it caused ...
Posted on May 11, 2018 at 07:37Is it possible to use BlurNRG BLE stack in STM32F103 CPU and use UART as a HCI interface to any Bluetooth chip?Read through BlueNRG manuals and those looks like BlueNRG is ment to be used only in SoC and ACI layer betw...
Posted on May 13, 2018 at 09:42Hi,I am confused by documentation of BlueNRG and various description of exiting from WFI for Cortex-M0.What is going on when BlueNRG-2 is woken up from deep sleep by external gpio pin?Is the program continuing executio...
