replay BLE advertisements from a Wireshark pcap

I am looking into replaying BLE packets (specifically advertisements) previously recorded with Wireshark and nRF sniffer

I wonder if such a "raw transmit" can be done with this library

this is how a BLE advertisement looks once recorded and exported as JSON from Wireshark (just the btle ad - full log attached):

  "btle": {
          "btle.access_address": "0x8e89bed6",
          "btle.advertising_header": "0x2560",
          "btle.advertising_header_tree": {
            "btle.advertising_header.pdu_type": "0x00",
            "btle.advertising_header.rfu.1": "0",
            "btle.advertising_header.ch_sel": "1",
            "btle.advertising_header.randomized_tx": "1",
            "btle.advertising_header.rfu.4": "0",
            "btle.advertising_header.length": "37"
          },
          "btle.length": "37",
          "btle.advertising_address": "d4:15:5c:77:56:68",
          "btcommon.eir_ad.advertising_data": {
            "btcommon.eir_ad.entry": {
              "btcommon.eir_ad.entry.length": "2",
              "btcommon.eir_ad.entry.type": "0x01",
              "btcommon.eir_ad.entry.flags.reserved": "0x00",
              "btcommon.eir_ad.entry.flags.le_bredr_support_host": "0x00",
              "btcommon.eir_ad.entry.flags.le_bredr_support_controller": "0x00",
              "btcommon.eir_ad.entry.flags.bredr_not_supported": "0x01",
              "btcommon.eir_ad.entry.flags.le_general_discoverable_mode": "0x01",
              "btcommon.eir_ad.entry.flags.le_limited_discoverable_mode": "0x00"
            },
            "btcommon.eir_ad.entry": {
              "btcommon.eir_ad.entry.length": "27",
              "btcommon.eir_ad.entry.type": "0xff",
              "btcommon.eir_ad.entry.company_id": "0x0499",
              "btcommon.eir_ad.entry.data": "05:10:ac:50:f7:bc:4a:00:48:00:28:03:fc:ad:96:68:31:19:d4:15:5c:77:56:68",
              "btcommon.eir_ad.entry.data_tree": {
                "_ws.expert": {
                  "btcommon.eir_ad.undecoded": "",
                  "_ws.expert.message": "Undecoded",
                  "_ws.expert.severity": "4194304",
                  "_ws.expert.group": "83886080"
                }
              }
            }
          },
          "btle.crc": "0xa96974"
        }

My idea would be to dump the JSON at an esp32 application, parse it and use esp-nimble-cpp to (re) transmit the capture

any suggestions how to go about it?

I could craft an NimBLEAdvertisementData from the above and transmit, but I wonder if there is a lower-level API which I could use in a more straightforward manner

thanks in advance for any suggestions
