通信に時々失敗してしまいます。

CANDY Pi Lite+D + Raspberry Pi 4
通常,電源投入2分後ぐらいで通信可能になるのですが、時々できない状態になる
その場合はリセットしないとダメでした。
通信できるときはLD1が点滅し2分後点滅が早くなりLD2が点滅し始めます。
通信できないときはLD1が点滅し2分後点滅が早くなるがLD2は消灯のままで失敗したと思われます。そのご再トライはしません。
何か回避策はあるのでしょうか?
お願いします。

ご質問ありがとうございます。

通信が途中でできなくなる場合ですと、電波圏外か電力不足が考えられます。

ラズパイを移動させていない場合は、ラズパイ本体の背面の赤色LEDが点滅しているか、あるいはターミナルから/var/log/syslogをご確認いただき、以下のような内容が出ているか確認していただけますか。

Jun 29 04:37:41 raspberrypi kernel: [114.391489] Under-voltage detected! (0x00050005)

赤色LED点滅または、上記ログが出ている場合は、電力不足となっています。このため、現状ご利用中の電流よりも大きい容量の電源をご用意ください。ラズパイ本体のUSB-Cから3A~4AのAC電源をご利用いただくか、CANDY Pi Lite+ DのDCジャックへ4AのACアダプター(対応する規格についてはこちらの「 DCジャック用ACアダプター」の項目をご覧ください)をご利用いただければと思います。

もし電源を解決しても事象が続く場合は、/var/log/syslogの内容のうち、問題が起こっている時間帯の内容を投稿していただければと思います。
よろしくお願いいたします。

logにはUnder-voltage detectedはありませんでした。
log情報は下記の通りです。

ありがとうございます。

CANDY RED側のログだけ出ておりますので、すでに接続が切れた後の状態かもしれません。
ターミナルから以下のようにCANDY Pi Lite用のサービスを再起動して、出てくるログを接続が切断されてしまうまでのものをいただけますでしょうか。

$ sudo candy service restart && tail -f /var/log/syslog

実行すると以下のようなメッセージが出てきます。以下は接続がうまくいった例ですので細かいところでは違いが出てきます。

なお、ご投稿いただいたログにあるようなエラーはこちらのラズパイ4では出ていないのですが、何かフローを実行したりBLEデバイスをUSB接続して使用していたりしますでしょうか?
特に使用されていない場合は、一旦以下のコマンドでCANDY REDを止めていただき、上記CANDY Pi Liteサービスの再起動コマンドの実行とログの取得を行なっていただければと思います。

$ sudo systemctl stop candy-red

通信失敗時のログになります。
今のところraspberrypi電源入り切りテストで10回中1,2回通信ができない状態になりますが
sudo candy service restart
で再起動するとできるようになります。再起動で失敗はないようです。
失敗時
sudo candy service status
をすると
candy-pi-lite.service - CANDY Pi Lite Service, version:7.0.3
Loaded: loaded (/lib/systemd/system/candy-pi-lite.service; enabled; vendor preset: enabled)
Active: inactive (dead)
と表示されました

ありがとうございます。

しかし、残念ながらCANDY Pi Liteのログが含まれておりません・・・
以下の方法で時間を特定して、その時間以降のログをご覧いただき、表示された結果の時間以降の内容を教えてもらえますか。このコマンドでは、CANDY Pi Liteが動き始めた時刻を特定するためのものです。

$ grep "Started CANDY Pi Lite Service" /var/log/syslog

例えばこの結果は、このような表示になります。

Mar 17 16:09:38 raspberrypi systemd[1]: Started CANDY Pi Lite Service, version:7.1.0.
Mar 17 17:44:52 raspberrypi systemd[1]: Started CANDY Pi Lite Service, version:7.1.0.
Mar 17 17:47:07 raspberrypi systemd[1]: Started CANDY Pi Lite Service, version:7.1.0.

上記のように結果が表示されますので、その中から事象が起こった時間に近い時間を調べていただき、/var/log/syslogのその時間以降の内容をいただければと思います。

また、以下の情報もいただけますでしょうか。

  • 利用されているOSイメージ(インストールしたRaspbianの種類)
  • CANDY Pi Liteの接続種類(USBかGPIOか)

もし、デスクトップGUIをご利用にならない場合は、Raspbian Liteをベースにした以下のOSイメージの利用もご検討いただければと思います。

お手数ですがよろしくお願いいたします。
