Posted on February 08, 2018 at 14:13I have done some research on G3-PLC based chips available on market and I selected to buy ST chips. So, could you provide some information about development firmware and all other stuff regarding for software deve...
So, After a couple days working. BlueNRG-MS do not answer on "scan request". All other functions work, i can connect/disconnect, write/read gatt properties... I work with Aci_Gap_Set_Discoverable. I found only one case for resolving. It is reboot. It...
If I changed the definition LS_SOURCE=LS_SOURCE_INTERNAL_RO, the procedure DeviceConfiguration() stopped in line "while(CKGEN_BLE->CLK32K_IT == 0);"It seems that the internal generator 32 kHz does not work.How I can to turn on generator 32 kHz.
