DIGITAL LOSS BER TESTER a tester is the device for removal, accumulation and information display about passings of a signal in radio amateur networks DMR, YSF, D-Star at observance of a condition that the radio station of the user carries out data exchange with network by means of the MMDVM device under control of the Pi-Star program.
The device consists of the client and server parts executed on microcontrollers of ESP-32, ESP-8266 series. The server addresses the Dashboard page of the Pi-star program, reads out indications of the last connection with an interval 5-10 with, transfers them to the server (IoT) ThingSpeak. A client part with an interval 10 with reads out data with ThingSpeak and brings them to the OLED monitor. A set of indications represents the sequence of the following attributes: call sign, connection time, BER value, Loss value. The platform of programming of ESP-32 and ESP-8266 is MicroPython.
When developing and debugging the author applied the following ready payments:
1. TTGO New WiFi Bluetooth Module 18650 Battery holder ESP32 4 MB SPI Flash 4 MB Psram 2A fuse
2. 868 мГц-915 мГц SX1276 ESP32 Lora 0.96 OLED Bluetooth WI-FI Lora
3. D1 mini - Mini NodeMcu 4M bytes Lua WIFI Internet of Things development board based ESP8266 by WeMos
All three payments are stitched under programming on MicroPython since payments come stitched under Arduino. The author used the EsPy.exe program.
The technique is in detail described here:
https://github.com/jungervin/EsPy
Posledniyeversiya of firmwares of MicroPython are downloaded from here:
http://micropython.org/download
On sale there are payments with hardwired Micropython, but the author did not test them.
The payment of SX1276 ESP32 Lora of 0.96 inches the blue OLED display is applied to a client part and it is required to write in it the Client.py file. Technique here: https://github.com/jungervin/EsPy.
Server part gathers according to the scheme:
