aci_gatt_exchange_config sometimes returns BLE_STATUS_NOT_ALLOWED with BlueNRG M2

I am using BlueNRG M2 and would like to increase the MTU size from default 23 to 100 bytes.After reading PM0257 programming manual, I tried calling aci_gatt_exchange_config function which sometimes returns BLE_STATUS_SUCCESS and sometimes throws BLE_...

There is a package named STSW-QUUPPA-ETAG when I am extracting the zip file the Middleware is not present in it due to which the IAR workbench is not able to build the project successfully.

What is the minimum pulse length for S2-LP GPIO to detect high level ?

I have configured a GPIO as input to control the RX or TX state, is there a minimum time above the high level threshold to respect or exceed the VDD/2+0,3 voltage is sufficient ?Thank you,Andy Rochette.

hci_reset function returns BLE_STATUS_TIMEOUT with BLUENRG-M2SA in network co-processor mode

I have BLUENRG-M2SA BLE module that I am trying to interface with STM32l496 IC.I generated the code through STM32CubeMX using X-CUBE-BLE2 v3.3.0 selecting HCL_TL Basic and HCL_TL_INTERFACE UserBoard.The code gets compiled and when I try to flash and ...

What is the power consumption of level shifter when only one power supply is applied ?

Hi,We are using the 54VCXH163245 in one of our designs. The chip has 3.3 V VCCA and 1.8 V VCCB. According to datasheet, VCCB must be powered before VCCA at startup. Have you done measurements on the current consumption of the device when VCCA is set ...

Does BlueNRG-2 allow bluetooth audio mesh network?

Does BlueNRG-2 allow bluetooth audio mesh network, in which a source (phone) connects to one end point, which acts as master towards another endpoint and this one being slave.

BLUENRG-M0A: Characteristics Overwritten when Specific UUIDs Are Used

Hello,I am writing some BLE firmware using the BlueNRG-M0A model on a Nucleo board to try and develop an understanding. To try and build an understanding, I am creating multiple services and characteristics with different functions (read only, read/w...
