I have quite an annoying problem keeping me from successfully deploying a bunch of NRF52 PIRs.
For a little while it works and then the messages stop. I have serial logs from the NRF52 seemingly sending the messages but nothing on the gateway side. The two devices are about 6 feet apart. I've tried it at home with a completely different pi and a completely different radio (pa and non-pa version) and the results are the same. On my desk at work its a regular pi b with a non-pa radio. Again, six feet apart. I've tried the default channel. I've tried channel 10 and 125 as well. I've tried max power and low power. I send the message twice thinking maybe one gets lost and the second makes it through.
Here's the sketch:
// SUMMARY: This demo sketch runs on the AM612 PIR v607 PCBto transmit battery voltage (heartbeat) and motion detections to a MySensors gateway using MySensors protocols.
// Note: because this is a passive node, node ID must be set manually to a unique sensor node ID:
#define MY_NODE_ID 70 // Passive mode requires static node ID
//#define MY_CORE_ONLY
//#define MY_PASSIVE_NODE
#define MY_RADIO_NRF5_ESB
/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.
