1. implemented HAL_StatusTypeDef HAL_FLASH_ReadWord(uint32_t Address, uint32_t* Data); and HAL_StatusTypeDef HAL_FLASH_ReadHalfWord(uint32_t Address, uint16_t* Data); which allows user to read the internal FLASH (with out read protection)
2. implemeted device_config struct to store device configurations, e.g. magnetometer fullscale, report period, etc.
3. added demonstration code of using flash reading apis in lora_demo.c, in which the configuration sent from the cloud is stored into the internal Data EEPROM bank1, and each time when the device is booted, the configurations would be loaded from the Data EEPROM and used to initialize the application.
1. added AT+ command "AT+MSGHEX" and change previous RHF76_ATCMD_FMT_SEND_MSGHEX to RHF76_ATCMD_FMT_SEND_CMSGHEX
2. implement send_unconfirmed with a non-breaking approach: added int (*send_unconfirmed)(const void *buf, size_t len); event handle in lora_module_st; added int tos_lora_module_send_unconfirmed(const void *buf, size_t len); in lora_module_wrapper.c; and implement static int rhf76_send_unconfirmed(const void *buf, size_t len) in RHF76.c
3. added { "+MSGHEX: PORT:", rhf76_incoming_data_process } in event array rhf76_at_event so that the device is able to process the downlink data when it is configurated to send unconfirmed message.
4. added AT+ command "AT+REPT", and implement the static int rhf76_set_repeat(uint8_t num) to enable user to set repeat times (1-15) while using "unconfirmed message"
5. updated the instructions of implemeting up-link parser and downlink parser on the server in the file "..\board\NUCLEO_STM32L073RZ\BSP\Src\lora_demo.c"
1. modified code in recv_callback, which allows user to set the fullscale magnetometer and report period
2. modified the sample javascript code for uplink and downlink data parser on the cloud
1. modified the HTS221: removed magic numbers, added a sensor_tempnhumi_t struct to accommodate temperature and humidity data
2. added .h and .c files for LIS3MDL magnetic sensor
3. added .h and .c files for LPS22HB pressure sensor
3. added IAR (EWARM) project for lorawan example
4. added bsp.c and bsp.h to manager the sensors
1. delete some junk files.
2. mqttclient added comments and updated to v1.0.2.
3. update README.md.
4. update the author's own server certificate.
5. minor changes to salof.
1. the address in tos_hal_sd_*(tos_hal_sd.c) is by byte, but address in HAL_SD_WriteBlocks/HAL_SD_ReadBlocks is by sector
2. convert address in tos_hal_sd_* from byte to sector( / 512)
