STM32WB55 ScanRequest stucks in hci_cmd_resp_wait forever after couple of hours of test
Hi everyoneI have ported p2pClient project to a custom board and kept it running for hew hours.I`m using the STM32Cube_FW_WB_V1.7.0 ilbraries and and imported system workbench project.Eveyrthing seems to be working but after 4 hours board was not res...
STM32WB55，on our customer board, ble statck init failed, but the code work well in demo board.
In the function Ble_Hci_Gap_Gatt_Init(), it stopped at hci_cmd_resp_wait(HCI_TL_DEFAULT_TIMEOUT);And does not advertising any signal.what the problem may be with my board.Thanks.
STM32WB55 locking up when characteristic value is altered
Hello,I am developing a system using an STM32WB55 Nucleo, such that the STM32 receives data from a Windows application via BLE changing of characteristic value, the STM32 then sends this over uart to an external device which returns an acknowledgemen...
