TinyGSMがSIMCOM社のSIM7080に対応したので早速使ってみました。
TinyGSMは色々な通信モジュールに対応したGSMのライブラリで、LTE通信にも対応しています。
以前QiitaにSIM7000とSIM7500でTinyGSMを使っ記事を書きました。
このころはまだSIM7080に対応していませんでした。
なおSIM7500JCとSIM7000JCの記事は
SIM7500JCでTinyGSMのHttpClientを動かしてみた
SIM7000JCでもTinyGSMのHttpClientを動かしてみた
となります。
今回は TinyGSM のサンプルプログラム
AllFunctions を使ってみました。
TinyGSMはこちらから入手できます。
Github TynyGSM
Arduino IDE に TynyGSM をインストールすると
ファイル → スケッチ例 → TynyGSMの中に AllFunctions があるので
このサンプルを開きます。
変更箇所
モデムの選択で
# define TINY_GSM_MODEM_SIM800 をコメントにして
# define TINY_GSM_MODEM_SIM7080 の先頭の // を消します。
59行目の
# define GSM_AUTOBAUD_MAX 57600
を
# define GSM_AUTOBAUD_MAX 115200
に変更
(自分が SIM7080G のボーレートを115200bps にしいるため)
91行目からのご自身が使用されるSIMに合わせて設定します。
自分はさくらセキュアモバイルSIM
使ったので以下のように書き換えました。
// Your GPRS credentials, if any
const char apn[] = "sakura";
// const char apn[] = "ibasis.iot";
const char gprsUser[] = "";
const char gprsPass[] = "";
128行目の
const int powerkey = 1; // SIM7080 powerkey
と 132行目から134行目までの
digitalWrite(powerkey,HIGH);
delay(2000);
digitalWrite(powerkey,LOW);
を追加
これはSIM7080G をアクティブにするために powerkey にパルスを加える処理です。
ご自身のハードウェアに合わせて下さい。
以上の変更を加えたプログラムです。
