please view the program, I first run SetTxMode() function, then run TxPacket() to execute Nrf905 transmission.
void TxPacket(unsigned char TxBUF[4])
{
Low_nrf905_CSN; // 使能Spi，允许对nrf905进行读写操作
Delay(1);
SpiReadSpiWrite(WTP); // 写数据前先写写数据命令
for (m=0;m<4;m++)

nrf905 433 mhz problem
Sorry, Frequency is 433Mhz.also attach my program for your reference.
by the way, may it judge that components and nrf905 hardware work properly if RF receive function work well? I want to confirm where problem is? hardware or software.
nrf905
Based on the attached design schematic, I made several samples, after test, it is found they all can well receive data, but can NOT send data out, I check its DR pin status before and after transmission, it became from low to high level, but standard receiver's CD AM DR always are low...
