Hi,How can I capture packets in my mesh on BlueNRG-2 module? How can I know if a module has passed any package to another module? I see packets directed to a specific module, but I don't see being an intermediary in the network.Regards Adam
I'm trying to develop a multiprotocol board with Dual Stack wM-Bus + NB-IOT. I found this link:https://www.st.com/en/wireless-connectivity/nb-iot-products.html So the ST87M01 module is capable of it. I have the next questions:1) The module is sold wi...

Hi, I am Driving an AMOLED display (GRAM) with QSPI.In blocking mode everythings works fine, but now I trying to "update" it using GPDMA, nothing works. Any advices ?So in blocking mode I used the typical : OSPI_RegularCmdTypeDef sCommand = {0}; sC...
Hi. I am using two STPM34 on my board, they are separated, UART, SCS, SYN, all of them. I got init issue happens at start-up. I can't detect it. I've applied this Getting started with the STPM3x document procedures and got driver code that provided b...
platform：BLUENRG345_MCSDK ：BLUENRG_LP_1.2.0Our device serves as a broadcaster (directional broadcast), with GATT acting as a server, providing one service and two characteristics(read_req and WriteReq). The target device will periodically connect to ...
Hello everyoneDo you know where can I find a ready to use example for X-NUCLEO-S2915A1 . It seems that everything is for other boards.I also tested P2P example from cube for L1 ("S2915A2_P2P") and it doesn't work . Two boards I press the button and n...
Hallo, I have in my middlewares BluNRG2 packet.I have this function aci_gatt_add_char that adds a characteristic that has ((uint8_t)CHAR_PROP_NOTIFY)|((uint8_t)CHAR_PROP_READ | CHAR_PROP_INDICATE) as Char_Properties.When this characteristic changes, ...
hello, as part of a project for a course I'd like to recover the sound intensity in random places. For this, I have 3 steval mksbox1V1 and I use the microphone mp23abs1 to recover the sound intensity in db of an environment. I'd like to place the car...
Hello Team,We have a STPM34-EVAL board and we are trying to interface 220V AC with it, Earlier the software worked well and were able to see all correct values, Now voltage seems to be messed up. Current detection is fine.Will you be able to provide ...
