Reading the Internal Temperature Sensor on #BL602 and BL604 ... All shall be explained in this article

RIOT OS on BL702? 🤔

#Roblox also happily renders #PineDio Stack BL604's Internal Temperature ... Received via #TheThingsNetwork 🎉

#Grafana receives #PineDio Stack BL604's Internal Temperature from #TheThingsNetwork ... And renders the Temperature Chart correctly 🎉

Let's create a command to transmit #PineDio Stack BL604's Internal Temperature to #TheThingsNetwork

#BL602 Internal Temperature Sensor is now read as a Float ... And first reading is always correct! 🎉

https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L31-L45

Here's how we call "get_tsen_adc" to read #BL602 Internal Temperature Sensor as a Float (instead of Integer)

https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L31-L45

Let's copy "bl_tsen_adc_get" from #BL602 ADC HAL and fix the issues ... 1️⃣ Temperature is now returned as Float (not Integer) ... 2️⃣ Insert a delay during init to fix the first reading

https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L47-L113

Reading #BL602 Internal Temperature Sensor with "bl_tsen_adc_get" has 2 issues ... 1️⃣ First reading is always too low ... 2️⃣ Result is returned as Integer even though the reading is actually Float

https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L15-L29

#BL602 ADC HAL provides a helpful function for reading the Internal Temperature Sensor: "bl_tsen_adc_get"

https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L1-L27

Reading the #BL602 Internal Temperature Sensor looks complicated ... But there's an easier way!

From #BL602 Reference Manual: The Internal Temperature Sensor is accessed thru ADC

I'll leave Cybersecurity to the pros 👍

I'm definitely better in C than .NET

Still remembered my .NET after all these years 🎉
