 Konfiguratsiya

1. To'g'ri qurilma bir vaqtning o'zida ko'pi bilan bitta asosiy qurilmaga ulanishi mumkin. Asosiy qurilma bir vaqtning o'zida ko'pi bilan bitta yordamchi qurilmaga ulanishi mumkin. Asosiy qurilma bir vaqtning o'zida ko'pi bilan bitta tobe qurilmaga ulanishi mumkin va eng ko'p bitta asosiy qurilmaga tobe qurilma sifatida ulanishi mumkin.
2. AT+CONNECT buyrug'i qurilma so'roviga ulanib bo'lmadi + ERR=3, iltimos, sabab uchun buyruq tavsifiga qarang;
3. Multi-ulanish avtomatik ravishda qayta ulanish uchun bir nechta qurilmalarni belgilaydi. Tengdosh qurilma g'ayritabiiy ravishda uzilib qolganda, modul avtomatik qayta ulanishni boshlaydi. Iltimos, ko'rsatmalar tavsifiga qarang;
4. CONNECTED P * X” yoki AT+CONNECT_LIST buyrug'i orqali? Qabul qiling );
5. Agar foydalanuvchi avtomatik ravishda qayta ulanishga sozlangan qurilmani faol ravishda uzish buyrug'idan foydalansa, avtomatik qayta ulanish yaroqsiz bo'ladi va keyingi g'ayritabiiy uzilishdan keyin kuchga kiradi.

Konfiguratsiya rejimi
Modul ikkita konfiguratsiya usulini qo'llab-quvvatlaydi: ketma-ket port konfiguratsiyasi va APP konfiguratsiyasi. APP konfiguratsiyasi, ya'ni modulni sozlash uchun mobil telefonda BLE APP dan foydalanish, avvalo AT+AUTH tekshirish parolini o'tkazishi kerak, ba'zi ko'rsatmalar APP konfiguratsiyasini yakunlashni qo'llab-quvvatlamaydi, batafsil ma'lumot uchun 5.3 Yo'riqnomalar jadvaliga qarang, faqat tekshirish o'tkazilgandan keyin boshqa AT buyruqlaridan foydalanish mumkin. APP konfiguratsiyasi autentifikatsiya davri ushbu ulanish uchun. Agar qurilma uzilib, qayta ulangan bo'lsa, qayta autentifikatsiya talab qilinadi. Konfiguratsiya rejimida, ketma-ket port AT buyrug'ini yuborganda, keyingi AT buyrug'ini yuborishdan oldin ketma-ket port qaytishini kutishingiz kerak.

MTU
MTU - bitta BLE paketining uzunligi. Standart maksimal qiymat 247, foydali yukning maksimal uzunligi esa 244.

After the connection is successful, the last number of the status print prompt string is the handle of the newly established connection, and the current transparent transmission also points to this handle; A single master role can connect to at most one slave role device; When the maximum number of connections is reached, using this command again will return +ERR=3, and you need to disconnect a connected device before connecting a new device; 3 seconds after printing the connection information , because it takes some time for the host to discover the service) before initiating the next connection, otherwise it will return +ERR=3.If the master role exceeds the maximum number of connections or the remote Bluetooth has established a connection with this module, using this command will directly return +ERR=3.
Example	Connect to the slave device with sequence number 5 in the parameter list returned by the AT+SCAN command Command: AT+CONNECT =5 return:+OK C1:02:03:04:05 CONNECTD C*1The connection specifies the MAC address C1:02:03:04:05 Command: AT+ CONNECT=, C1:02:03:04:05return:+OK C1:02:03:04:05 CONNECTD C*1

Uskuna dizayni

• Modulni quvvatlantirish uchun doimiy ravishda regulyatsiya qilinadigan quvvat manbaidan foydalanish tavsiya etiladi. Elektr ta'minotining dalgalanma koeffitsienti imkon qadar kichik bo'lishi kerak va modul ishonchli tarzda erga ulangan bo'lishi kerak.
• Iltimos, elektr ta'minotining ijobiy va salbiy qutblarini to'g'ri ulashga e'tibor bering. Teskari ulanish modulning doimiy shikastlanishiga olib kelishi mumkin.
• Tavsiya etilgan quvvat manbai hajmiga to'g'ri kelishiga ishonch hosil qilish uchun quvvat manbaini tekshiringtage. Agar u maksimal qiymatdan oshsa, modul doimiy ravishda buziladi.
• Iltimos, quvvat manbai barqarorligini tekshiring. jildtage ko'p yoki tez-tez o'zgarib turmasligi kerak.
• Modul uchun elektr ta'minoti sxemasini loyihalashda ko'pincha 30% dan ortiq marjni saqlab qolish tavsiya etiladi, bu butun mashinaning uzoq muddatli barqaror ishlashiga yordam beradi;
• Modulni quvvat manbalari, transformatorlar va yuqori chastotali simlar kabi katta elektromagnit parazitlarga ega bo'lgan qismlardan iloji boricha uzoqroq tutish kerak;
• Modul atrofida katta elektromagnit parazitlarga ega qurilmalar mavjud bo'lsa, bu modulning ishlashiga ham katta ta'sir qiladi. Interferentsiyaning intensivligiga qarab ularni moduldan uzoqroq tutish tavsiya etiladi. Iloji bo'lsa, tegishli izolyatsiya va ekranlash amalga oshirilishi mumkin.
• Agar modul atrofida katta elektromagnit parazitlarga ega bo'lgan izlar (yuqori chastotali raqamli, yuqori chastotali analog, quvvat izlari) mavjud bo'lsa, bu modulning ishlashiga ham katta ta'sir qiladi. Interferentsiyaning intensivligiga qarab ularni moduldan uzoqroq tutish tavsiya etiladi. Iloji bo'lsa, tegishli izolyatsiya va ekranlash amalga oshirilishi mumkin.
• USB2.4 kabi jismoniy qatlami ham 3.0 gigagertsli bo'lgan ba'zi TTL protokollaridan uzoqroq turishga harakat qiling;
• Antennani o'rnatish tuzilishi modulning ishlashiga katta ta'sir ko'rsatadi. Antenna ochiq va afzal vertikal yuqoriga qarab turganligiga ishonch hosil qiling. Modul korpus ichiga o'rnatilganda, antennani korpusning tashqi tomoniga cho'zish uchun yuqori sifatli antenna uzatma kabelidan foydalaning;
• Antennani metall qobiq ichiga o'rnatmaslik kerak, chunki bu uzatish masofasini sezilarli darajada kamaytiradi.

 Tez-tez so'raladigan savollar

1. Etkazish masofasi ideal emas
   • To'g'ri chiziqli aloqa to'sig'i mavjud bo'lganda, aloqa masofasi mos ravishda susayadi;
   • Harorat, namlik va ko-kanal shovqinlari aloqa paketini yo'qotish tezligini oshirishi mumkin;
   • Er radio to'lqinlarini o'zlashtiradi va aks ettiradi, shuning uchun erga yaqin bo'lganda sinov natijalari yomon;
   • Dengiz suvi radio to'lqinlarini singdirish qobiliyatiga ega, shuning uchun dengiz qirg'og'ida sinov effekti yomon;
   • Agar antenna yaqinida metall buyumlar bo'lsa yoki antenna metall qobiqqa joylashtirilsa, signalning susayishi juda jiddiy bo'ladi;
   • Quvvat registri noto'g'ri o'rnatilgan yoki havo tezligi juda yuqori o'rnatilgan (havo tezligi qanchalik baland bo'lsa, masofa yaqinroq);
   • Elektr ta'minoti voltage xona haroratida tavsiya etilgan qiymatdan past. Volt qancha past bo'lsatage, quvvat chiqishi qanchalik past bo'lsa.
   • Amaldagi antenna modulga mos kelmaydi yoki antennaning o'zida sifat muammosi mavjud.
2. Modullar shikastlanishga moyil
   • Tavsiya etilgan quvvat manbai hajmiga to'g'ri kelishiga ishonch hosil qilish uchun quvvat manbaini tekshiringtage. Agar u maksimal qiymatdan oshsa, modul doimiy ravishda buziladi.
   • Iltimos, quvvat manbai barqarorligini tekshiring. jildtage juda ko'p yoki tez-tez o'zgarib turmasligi kerak.
   • Iltimos, o'rnatish va ishlatish vaqtida antistatik ishlamasligiga ishonch hosil qiling, chunki yuqori chastotali komponentlar statik elektrga sezgir;
   • Iltimos, o'rnatish va ishlatish vaqtida namlik juda yuqori bo'lmasligiga ishonch hosil qiling, chunki ba'zi komponentlar namlikka sezgir qurilmalardir;
   • Agar maxsus talab bo'lmasa, uni juda yuqori yoki juda past haroratda ishlatish tavsiya etilmaydi.
3. Bit xatolik darajasi juda yuqori
   • Yaqin atrofda bir xil chastotali signaldan shovqin bor. Interferentsiyani oldini olish uchun shovqin manbasidan uzoqroq turing yoki chastota yoki kanalni o'zgartiring.
   • Qoniqarsiz quvvat manbai ham buzilgan belgilarga olib kelishi mumkin, shuning uchun elektr ta'minotining ishonchliligini ta'minlash kerak;
   • Sifatsiz yoki juda uzun uzaytiruvchi kabellar yoki oziqlantiruvchi kabellar ham yuqori bit xato tezligiga olib kelishi mumkin.
