Posted on May 17, 2018 at 10:27Hi,I'm using a SPWF04Sx WIFI module.In AT.HTTPOST command there isn't a field for a JSON payload, but I really need it.There is something that allow me to send a JSON payload ?There isn't also a field for the call's he...
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...
