本人是個(gè)人愛(ài)好者，使用CH571F芯片，自己設(shè)計(jì)的PCB板子，沒(méi)有設(shè)計(jì)外部32K晶振，采用內(nèi)部RC作為32K時(shí)鐘源，使用鍵盤(pán)例程進(jìn)行改動(dòng)，發(fā)送數(shù)據(jù)時(shí)藍(lán)牙老是斷開(kāi)，通過(guò)BLE助手查看板子的信號(hào)強(qiáng)度在-37dB，不知道是什么問(wèn)題，目前已經(jīng)嘗試調(diào)整過(guò)，望解答一下。藍(lán)牙斷開(kāi)原因的reason的參考手冊(cè)從哪兒??？

BLE_BUFF_MAX_LEN=251

BLE_TX_NUM_EVENT=4

CLK_OSC32K=2

// Minimum connection interval (units of 1.25ms)

#define DEFAULT_DESIRED_MIN_CONN_INTERVAL? ? ?15//8

// Maximum connection interval (units of 1.25ms)

#define DEFAULT_DESIRED_MAX_CONN_INTERVAL? ? ?45//8
