Hi,I'm working on the new BlueTile board (STEVAL-BCN002V1B) including a BlueNRG-2 module. According to documentation, BlueNRG-2 should support data length extension from Bluetooth 5.0. Has this feature already been added to the SDK ?It seems that th...
Hello.There is a schematic for using BlurNRG-232 (QFN-32) with the balun BALF-NRG-02D3 in the datasheet for BlueNRG-2. The STEVAL-IDB008V2 (BlurNRG-232) was done with BALF-NRG-02D3. The schematic of STEVAL-IDB009V1 (BlurNRG-248) was done without the ...
I try to use the BlueNRG in conjunction with the FreeRTOS but the system always ends up in a hardfault as soon as I querry the BLE services.The initialization of the BlueNRG works and establishing a connection works as well. But it seems like any use...
I cannot find any related information for this.It seems like evt_gatt_attr_notification->attr_value always has 2 bytes leading zeros.This means if a write a char value with Attribute_Val_Length = 0x02 and Attribute_Val = 0xCAFE I get a attr_value of ...
Hi,I want to connect the BlueNRG-2 evaluation board (STEVAL-IDB008V2) to a standard bluetooth dongle in a standard PC and let the PC receive some data like numbers between 0 and 255 from the BlueNRG-2 device. Can’t find out how. Can anybody help?
