The transmitting period is very short, so this may be the reason why they are running without being destroyed.

Hello Ttelmah, I used the RFM12B which are rated at 3.6V.
There is no charging in the devices, but fresh charged LiIon cells do have a voltage of about 4.05....4.09V at the beginning.
No RFM12B devi ...

Hello temtronic,
The life span should be as long as possible, it would be good to make the device running approx. 1 year without changing/charging battery.
The device is running inside, so the tempe ...

Back to the topic: a battery powered 18 pin count PIC (e.g. 16F1847) should wake up from sleep frequently with a period of 10min. There is no trigger from outside, there is no external oscillator/crys ...

Hello temtronic,

I cannot use a larger capacity battery, the size is limited to a CR2/3 / 16340 LiIon cell. The max capacity is around 700...800 mAh.

I cannot use 'L' version because the voltage ...

Hello, now I checked the data sheet:

21.4 Timer1 Oscillator
A dedicated low-power 32.768 kHz oscillator circuit is
built-in between pins T1OSI (input) and T1OSO
(amplifier output). This internal ...

Hello PCM programmer, did you use an external oscillator?
I tried your code using a PIC16F1847 with an internal oscillator, it does not run.
May it be that the internal oscillator does not run in sl ...

Hello PCM programmer, many thanks, I will try it soon!

Hello temtronic, thanks for the hint regarding using a timer instead of WDT! The chip I'm using is 16F1847.

Hello Ttelmah, thanks for the info!

The timing reqired changes, 10 sec, 20 sec, 1 min ...

Hello,

For an application the PIC should go into sleep mode to save energy and wake up frequently from sleep without any input from outside the PIC.
The sleep time may vary between several 10s of ...

I will take an 18F27J13, program memory size should not be a problem as the code to read out the sensors is small.

Hello,

I'm also looking for a CCS LoRaWAN library.
At the moment I'm using RFM95 modules sucessfully in LoRa mode, but only point to point.
For another project I think using LoRaWAN together with ...

Hello,

I got the modules running.

I choosed the LORA transceiver modules of RF-Solution because of the range up to 16km, I do not need a high transmission rate.

Hello,

Does anybody have experiences using LORA / SX1272 in LORA mode?
I would like to replace an RFM69 module by a LORA / SX1272 module.
The communication between PIC16F1827 via SPI is running p ...

Hello,

I got it, now it's running well.

But one question left: why should I change FLASH_SIZE in the driver to 16777216? It's a 64MBit memory, so the size should be 64*1024*1024/8 (8 Bit = 1 Byt ...
