Wireless Module: Communication Function Test

NiceRF: Wireless Module Communication Function Test

Preparation tools:

1. Two DEMO function demo boards embedded with wireless module LoRa1276F30

2. Two batteries (voltage: 3.7V,  current: 1200mA)

Wireless module test process:

There are three power supply modes for our DEMO function demonstration board:

1. 4 AA batteries can be installed on the back

2. DC connector

3. Pin interface

Now use the third power supply method, the pin is four pins, the red positive black negative of the electric board is correctly inserted into the second and third pins, and the power is turned on.

Turn on the power switch and find that the TX numbers are superimposed, and the red light flashes at intervals, indicating that the demo version of the DEMO function is transmitting data to the outside world.

Next, we set the two demo boards to TX Normal, RX Normal, FREQ to 891.5MHz, RPW to 7, CR to 45, SF to 12KHz, BW to 500KHz, and the setup is complete.

The left and right sides of the DEMO function demonstration board interface RX value is 0065, which is consistent, and TX is 0086 and 0065 respectively. Because NiceRF initially set the parameters of the left demo board, and then set the right demo board, so the TX value of the left demo board is larger than the right one, and the wireless module communication function detection is completed.
