Bug in the official P2P example for S2-LP radios included X-CUBE-SUBG2 package As of version 1.1.0 of X-CUBE-SUBG2, file app_x-cube-subg2.c contains two uninitialized pointers. typedef struct
{
uint8_t Cmdtag;
uint8_t CmdType;
uint8_t CmdLen;
uint8_t Cmd;
uint8_t DataLen;
uint8_t* DataBuff; // This pointer
}AppliFrame_t;DataBuff of two instances of AppliFrame_t, xTxFrame, xRxFrame, were operated on without initialization. for (xIndex = 5; xIndex < cRxlen; xIndex++)
{
xRxFrame.DataBuff[xIndex] = pRxBuff[xIndex];
}for(; xIndex < xTxFrame->DataLen; xIndex++)
{
TxFrameBuff[xIndex+5] = xTxFrame->DataBuff[xIndex];
}As a result, the example basically doesn't work. System will just crash upon running. Tested on several NUCLEO boards, F411RE, F070RB, but judging from source code, other nucleo boards will be affected as well, including L152 and L052 boards which are supposedly fully tested.Given S2-LP radios are basically brand new, we spent hours and hours making sure we followed the instruction correctly to no avail before we started to check the
