I have a low power setup of rfm95 and atmega328p running off two coincell batteries through (stepped down to 3.3v). So I can get you 10uA sleep current. I am using Sandeep’s Lora libarary. All is well until suddenly all other functions work except the radio. When power cycled all works again.
I am suspecting that somehow the reset pin is being triggered on rfm95. I have added a setup which puts the reset pin as an output with high impedance but still the same problem.
Any idea I a fix or course if inquiry will be very much appreciated!
First of all many thanks for your prompt response. I’m afraid I am guilty of believing comments on somebody else code:
/* RFM reset pin is 9
* A manual reset of the RFM69HCW\CW is possible even for applications in which VDD cannot be physically disconnected.
* Pin RESET should be pulled high for a hundred microseconds, and then released. The user should then wait for 5 ms
* before using the module.
//reset RFM module
// set Pin 9 to high impedance
So I will disconnect the reset and try. Do you think adding a pull down resistor help?
