BLE Serial Pro

With this serial UART terminal app it is possible to communicate via Bluetooth Low Energy between ESP32, Arduino, Raspberry pi or other PC's equipped with Nordic nRF or Texas Instruments CC2541 MCU’s.
ESP32 board and Arduino/Raspberry RP2040, Arduino Nano BLE 33, and Arduino SAMD boards like the MKR1010 have built in BLE MCU’s.

With this PRO version it is possible to choose between the two BLE protocols . 

The app transmits and receives strings between the connected BLE device with a large window containing received data and an edit line for typing in strings to transmit.

Unlike most apps strings over 20 bytes are not truncated making is possible to use descriptive menu's to communicate with the BLE equipped computer.

The app runs on a Mac mini with M1 processor, iPad or iPhone and connects to the CC2541 and nRF devices.
Tested are:
CC2541 chipset: HM-10, JDY-23
nRF chipset: Arduino MKR1010, Arduino Nano 33 IOT, Nano RP2040.

With this PRO version buttons can be programmed with formats like UTF8 strings, hexadecimal, decimal, octal and binary commands that can be repeated at a give frequency or only once. 
The buttons can be arranged on the display. 

Received messages can be exported.
Alarms can be programmed on contents of received messages in all kind of formats.

The display window with received messages has many options to 
- display messages five formats (UTF8, Dec, Hex, Octal, Bin) 
- font size, 
- time stamp, 
- auto scroll, 
- clear window on new message, 
- time stamps.
