External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol. 246 246 336 +Each LA66 module includes a (% style="color:blue" %)**world-unique OTAA key**(%%) for LoRaWAN registration. 247 247 338 +Besides the support of the LoRaWAN protocol, LA66 also supports (% style="color:blue" %)**open-source peer-to-peer LoRa Protocol**(%%) for the none-LoRaWAN application. 248 248 249 - ====(% style="color:blue" %)**Download andInstallApp:**(%%)====340 +LA66 is equipped with (% style="color:blue" %)**TCXO crystal**(%%) which ensures the module can achieve stable performance in extreme temperatures. 250 250 251 251 252 -[[(% id="cke_bm_895007S" style="display:none" %)** **(%%)**Download Link for Android apk **>>https://www.dropbox.com/sh/zxwx16qb777uvkz/AABE_P8coGCQ4DAC8enH4bUya?dl=0]].
