Hi,my friend,
Now,I use nrf905.Situation is as follows: I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data. 1.The Product host is to use the stick antenna,the Product unit is to use the stick antenna. 2.Use 433 MHZ communication,100 KPS transmission speed, crystals with 16 MHZ. 3.Unit and host communications,Effective distance less than 40 meters.In 10 meters range, again and again to send and receive data, found that often lost data. 4.Reached the maximum transmitted power,+10DBM.Reached the highest receiving sensitivity.
1.Why is this so? 2.How do I solve? 3.Add external PA, can increase the distance, can solve the lost data?
