Posted on May 22, 2018 at 08:43Hello everyone,We are using the SPBTLE-1S on a simple PCB and we followed all PCB guidelines. Today i measured the distance we can communicate between the PCB and an Android App (a random from App Store) on my mobile p...
Posted on May 22, 2018 at 00:05Hi, I am using Bluetooth module SPBT3.0DP2 and it worked fine during development. Currently we are in production stage and we have populated 80 boards with Bluetooth module. 20 Bluetooth modules are not working as expe...
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...
