iBeacon Sensor Application for nRF52 with Apache Mynewt and Embedded Rust

This nrf52 branch contains the source code for an iBeacon Sensor Application for nRF52 with Apache Mynewt and Embedded Rust that has been tested on the EBYTE E73-TBB Development Board. Refer to the tutorial...

Coding nRF52 with Rust and Apache Mynewt on Visual Studio Code

Fixes for Mynewt type conversion build warnings

These fixes should be applied manually when upgrading Mynewt or installing Mynewt from scratch.

1️⃣ repos/apache-mynewt-core/kernel/os/include/os/os_mutex.h line 122

    return mu->mu_level;

Change to

    return (os_error_t) mu->mu_level;

2️⃣ repos/apache-mynewt-core/hw/sensor/include/sensor/sensor.h line 847

    return (sensor->s_types & sensor->s_mask & type);

Change to

    return (sensor_type_t) (sensor->s_types & sensor->s_mask & type);

3️⃣ repos/apache-mynewt-core/encoding/tinycbor/include/tinycbor/cbor.h line 201

    {   return encoder->writer->bytes_written; }

Change to

    {   return (CborError) encoder->writer->bytes_written; }

How This Application Was Created

The Windows version of the newt command-line tool in newt/newt.exe was created from

github.com/lupyuen/mynewt-newt

The Mynewt application was originally based on:

mynewt.apache.org/latest/tutorials/sensors/sensor_thingy_lis2dh12_onb.html

mynewt.apache.org/latest/tutorials/sensors/sensor_nrf52_bno055.html

cd /mnt/c
newt new stm32bluepill-mynewt-sensor
cd stm32bluepill-mynewt-sensor
cat project.yml

newt install
newt pkg new -t app apps/my_sensor_app
newt pkg new -t lib libs/semihosting_console

newt target create bluepill_boot
newt target set bluepill_boot bsp=@apache-mynewt-core/hw/bsp/bluepill
newt target set bluepill_boot app=@apache-mynewt-core/apps/boot
newt target set bluepill_boot build_profile=optimized

newt target create bluepill_my_sensor
newt target set bluepill_my_sensor bsp=@apache-mynewt-core/hw/bsp/bluepill
newt target set bluepill_my_sensor app=apps/my_sensor_app
newt target set bluepill_my_sensor build_profile=debug
