Hello,

I try to get running the nice FOTA feature (I love it to use on ESP32). I have a pro mini 8MHz 3.3V node with NRF24L01+. Sometimes I get an sucessful upload of a new sketch and sometimes it takes very long time (over 5min) or it takes long time until myscontroller finds the node. I have the feeling that there are some corners where I could or was turned in the false direction. It resulted in several long nights...

I have 4 topics in mind to the problem:

1. github repo
   Shall I use the the development branch for mysbootloader on github? I wanted to avoid compiling the bootloader and only use the ready hex-files because I'm shure that I trip in some pitfalls. I read somewhere that with development branch it is still possible to use serial upload and with main branch not.
   Gernerally I could live with main branch but there is only one hex-file and I do not know for which HW it is. And then there is a third branch UpdateBoardFiles. I did not understand for what it is.
2. two 8MHz Versions
   I noticed that there are two 8MHz hex-Files and Entries. I took the NRFduino because the fuses are similar to normal pro mini. Is it the right one?
3. fuses
   I noticed that in all 4 entries the extended_fuses=0x06. This is completely another value than in the "normal" pro mini bootloader. I had a look at the atmega328P data sheet and saw that only 3 lower bits are defined for brown out feature and these combination of the lower 3 bits is reserved. Is there any reason for that?
4. time until sketch is started
   I wrote a simple blink sketch (with using millis for delay - my first pitfall) and later with deactivating watchdog (second pitfall). Now I wonder because of long (10s-1min) and various time until the sketch is started. I could isolate a little bit: If I cut the SCLK connection to to NRF it starts instantly. Without NRF and only powered with 2xAA cells too. Yes I understand that the bootloader has to check for a message from controller but why with a variable time although I have not a switched on/powered GW?
   As another cause I found the serial/USB connection. If I power the node via a TTL/USB Converter at an Windows USB port (to read serial outputs) it also takes long time to start. If I plug these vehicle to an USB powerbank it starts instantly too.
   Is these behave explainable?

Many thanks for some helpfull hints in advance!

Great, that was the right hint. Now I get values. Thanks!!!

But should it included in the example code? I had a look in the development branch. There it was fixed. But in the development -3.0.0 branch not.

Hello,

I'm running since some weeks a serial GW (based on Nano) and some nodes (based on pro mini) with RFM69HW. I use lib version 2.3.2 and tried to get running the RFM69_RFM95_ATC_SignalReport.ino example. I only changed in the sketch the definition to RFM69HW (refer git diff report at the end) and put the sketch to a node. At the GW I additionally added #define MY_RFM69_NEW_DRIVER. The communication is working.

The problem is that all 6 return values of transportGetSignalReport are always zero.

Has anybody a hint for me what I do not in the right way?

Thanks for an answer in advance.
Uwe
