# WisBlock-API-V2
----
Arduino library for RAKWireless WisBlock Core modules that takes all the LoRaWAN, BLE, AT command stuff off your workload. You concentrate on your application and leave the rest to the API. It is made as a companion to the [SX126x-Arduino LoRaWAN library](https://github.com/beegee-tokyo/SX126x-Arduino)

  - Tested with desktop version of [RAKwireless WisToolBox](https://docs.rakwireless.com/Product-Categories/Software-Tools/WisToolBox/Overview/)
  - Not yet working with mobile version of WisToolBox (Device sync fails, but BLE UART terminal can be used already)

## 1.1.18 Add Cayenne LPP and cleanup AT commands
  - Add WisBlock extended Cayenne LPP to make it easier to use from examples
  - Replace AT command SENDFREQ with SENDINT to make it's meaning easier to understand (use word interval instead of frequency)

## 1.1.17 Add RAK11200 support and fix AT command manual
  - Add experimental support for RAK11200    
  - Correct AT command manual    
  
## 1.1.16 Small improvements
  - Make AT commands accept lower and upper case
  - AT+BAT=? returns battery level in volt instead of 0 - 254
  - BLE name changed to part of DevEUI for easier recognition of a device
  - Change ADC sampling time to 10 us for better accuracy

## 1.1.15 Remove external NV memory support
  - Removed support for external NV memory. Better to keep this on application level

## 1.1.14 External NV memory support
  - Add support for external NV memory. Prioritize usage of external NV memory over MCU flash memory.
  
## 1.1.13 Fix LoRa P2P bug
  - In LoRa P2P the automatic sending did not work because g_lpwan_has_joined stayed on false.
  
## 1.1.12 Fix timer bug
  - If timer is restarted with a new time, there was a bug that actually stopped the timer
  
## V1.1.11 Fix long sleep problem
  - Define alternate pdMS_TO_TICKS that casts uint64_t for long intervals due to limitation in nrf52840 BSP
