BlueNRG - how to reject a read request

Hello,   I have a problem by using event to catch a read of a characteritics. When I'm in the event EVT_BLUE_GATT_READ_PERMIT_REQ I want to deny the read. I see only the function aci_gatt_allow_read and not any function like aci_gatt_deny_read. On go...

Change transmit (Tx) interval for LoRaWAN software

Hello!I have a NUCLEO-L073RZ development board, with the SX1272MB2DAS LoRa RF expansion board (from Semtech). I have downloaded code for it here at ST at: https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm...

SPIRIT1. Need assistance on initial register values to set up a simple point to point 915 MHz link. Any app notes available for this start up?

Avertising UUIDs for BLE

Hello,Is it possible to advertise my UUIDs services when my Bluetooth device is in advertising mode?I am using STM32 and SPBTLE-RF0TR in my application. I have 2 primary services (16 BITS UUID) and 2 customer services (128 BITS UUID). I have succeede...

Difference between using X-NUCLEO-IDW01M1 and SWPF01SA

I'm trying to interface my STM32 board(STM32L476JGY to be specific) with a Wifi chip using UART.At first, I looked into ESP8266, but I wasn't able to find that much resource on it. There are some Arduino libraries, but I don't really know the best wa...

STOTG04E Timing constraints of OE_TP_INT/ signal and Data paths. Setup time vs Bus turnaround time.

Product: STOTG04E USB OTG LS/FS PHYWhat is the difference between the idle and output state when the oe_tp_int/ signal is high?My rec_bias_en bit from the Control Register 3 is low. (i.e transmit bias circuitry is disabled during the receive mode), a...

What is the topside marking of the STWLC68JRH?

STEVAL-IDB007V1M, SPBTLE-1S Not working

Hi,I have bought a STEVAL-IDB007V1M so i can learn how to incorporate BLE into my project but im having problems. The board isn't being picked up on BlueNRG-1 Navigator but it is being picked up on BlueNRG-2 Navigator. - Im not sure if this is a prob...

BLE_SensorDemo sensor updates to ST BLE Sensor app: I would like to increase the update frequency of BCN002V1 tile sensors (in particular the proxiity sensor) to the app. I'm looking for the timing code that controls the updates to the Android/iPhone app.

I can't get the data transmitted faster than every 487ms or about 0.5s. And that's with the Motion Sensor Update Rate set to 40Hz. I've set the DM (Distance Mode) to short (=1), the TimingBudget to 20 ms and the InterMeasurement down to 25ms. The rel...
